Doublecortin-like domain found in doublecortin domain-containing protein 1 (DCDC1); Doublecortin (DCX) is a microtubule-associated protein (MAP) with a stable ubiquitin-like tertiary fold. Microtubules are key components of the cytoskeleton that are involved in cell movement, shape determination, division and transport. DCX gene family consists of eleven paralogs in human and mouse, such that its protein domains can occur in tandem or single repeats. Proteins with DCX tandem domains in general have roles in microtubule (MT) regulation and signal transduction while single DCX repeat proteins are normally localized to actin-rich subcellular structures or to the nucleus. DCDC1 is a hydrophilic intracellular protein that contains only one DCX repeat. Therefore, DCDC1 might only bind to microtubules without microtubule polymerization properties. DCDC1 is mainly expressed in adult testis.

ricin B-type lectin domain, beta-trefoil fold; The ricin B-type lectin domain is a carbohydrate-binding domain formed from presumed gene triplication. It shows a beta-trefoil fold characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain was originally found in Ricin, which is a legume lectin from the seeds of the castor bean plant, Ricinus communis. It is also found in many carbohydrate-recognition proteins like plant and bacterial AB-toxins, glycosidases, or proteases, which serve diverse functions such as inhibitory toxicity, enzymatic activity, and signal transduction. The ricin B-type lectin domain can be present in one or more copies and has been shown in some instances to bind simple sugars, such as galactose or lactose. The most characteristic, though not completely conserved, sequence feature is the presence of a Q-W pattern. Consequently, the ricin B-type lectin domain has also been referred as the (QxW)3 domain and the three homologous regions as the QxW repeats. A disulfide bond is also conserved in some QxW repeats.

GllA-1 domain, beta-trefoil fold, found in Mucor circinelloides Gellins and similar proteins; Gellin proteins act as central effectors of wound-induced protoplasmic gelation. They possess ten related N-terminal beta-trefoil domains (Gll-1 to Gll-10) that contribute to distinct gelation-related activities. The beta-trefoil domains show low sequence similarity to members of the functionally diverse ricin B lectin domain family. They are characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain bears a potential sugar binding site. Gellin from M. circinelloides has been called GellinA (also known as GllA). The model corresponds to GllA-1 domain, which is a remote family member of the ricin B-type lectin domain.

Microtubules are key components of the cytoskeleton that are involved in cell movement, shape determination, division and transport. The DCX gene family consists of eleven paralogs in human and mouse, and its DCX protein domains can occur in double tandem or as single DCX repeats. Proteins with DCX tandem domains in general have roles in microtubule (MT) regulation and signal transduction such as X-linked doublecortin (DCX), retinitis pigmentosa-1 (RP1) and doublecortin-like kinase (DCLK). Single DCX repeat proteins are normally localized to actin-rich subcellular structures, or the nucleus such as DCDC2. DCX is not only a unique MAP in terms of structure, it also interacts with multiple additional proteins. Mutations in human DCX genes are associated with abnormal neuronal migration, epilepsy, and mental retardation.

GllA-1 domain, beta-trefoil fold, found in Mucor circinelloides Gellins and similar proteins; Gellin proteins act as central effectors of wound-induced protoplasmic gelation. They possess ten related N-terminal beta-trefoil domains (Gll-1 to Gll-10) that contribute to distinct gelation-related activities. The beta-trefoil domains show low sequence similarity to members of the functionally diverse ricin B lectin domain family. They are characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain bears a potential sugar binding site. Gellin from M. circinelloides has been called GellinA (also known as GllA). The model corresponds to GllA-1 domain, which is a remote family member of the ricin B-type lectin domain.

Doublecortin-like domain found in doublecortin domain-containing protein 1 (DCDC1); Doublecortin (DCX) is a microtubule-associated protein (MAP) with a stable ubiquitin-like tertiary fold. Microtubules are key components of the cytoskeleton that are involved in cell movement, shape determination, division and transport. DCX gene family consists of eleven paralogs in human and mouse, such that its protein domains can occur in tandem or single repeats. Proteins with DCX tandem domains in general have roles in microtubule (MT) regulation and signal transduction while single DCX repeat proteins are normally localized to actin-rich subcellular structures or to the nucleus. DCDC1 is a hydrophilic intracellular protein that contains only one DCX repeat. Therefore, DCDC1 might only bind to microtubules without microtubule polymerization properties. DCDC1 is mainly expressed in adult testis.

ricin B-type lectin domain, beta-trefoil fold; The ricin B-type lectin domain is a carbohydrate-binding domain formed from presumed gene triplication. It shows a beta-trefoil fold characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain was originally found in Ricin, which is a legume lectin from the seeds of the castor bean plant, Ricinus communis. It is also found in many carbohydrate-recognition proteins like plant and bacterial AB-toxins, glycosidases, or proteases, which serve diverse functions such as inhibitory toxicity, enzymatic activity, and signal transduction. The ricin B-type lectin domain can be present in one or more copies and has been shown in some instances to bind simple sugars, such as galactose or lactose. The most characteristic, though not completely conserved, sequence feature is the presence of a Q-W pattern. Consequently, the ricin B-type lectin domain has also been referred as the (QxW)3 domain and the three homologous regions as the QxW repeats. A disulfide bond is also conserved in some QxW repeats.

ricin B-type lectin domain, beta-trefoil fold, found in the polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3)-like subfamily; The GALNT3-like subfamily includes GALNT3, GALNT4, GALNT6 and GALNT12. They act as GalNAc transferases (EC 2.4.1.41) that catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT3 has activity toward HIV envelope glycoprotein gp120, EA2, Muc2 and Muc5. It probably glycosylates fibronectin in vivo as well as FGF23. It plays a central role in phosphate homeostasis. GALNT4 shows highest activity towards Muc7, EA2 and Muc2, with a lower activity compared to GALNT2. It glycosylates 'Thr-57' of SELPLG. GALNT6 may participate in the synthesis of oncofetal fibronectin. It has activity toward Muc1a, Muc2, EA2 and fibronectin peptides. GALNT12 has activity toward non-glycosylated peptides such as Muc5AC, Muc1a and EA2, and no detectable activity with non-glycosylated Muc2 and Muc7. It displays enzymatic activity toward the Gal-NAc-Muc5AC glycopeptide, but no detectable activity to mono-GalNAc-glycosylated Muc1a, Muc2, Muc7 and EA2. It may play an important role in the initial step of mucin-type oligosaccharide biosynthesis in digestive organs. Members of this family comprise a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which are characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.
