ERGIC-53 and ERGL type 1 transmembrane proteins, N-terminal lectin domain; ERGIC-53 and ERGL, ...
 44-268 4.88e-174

ERGIC-53 and ERGL type 1 transmembrane proteins, N-terminal lectin domain; ERGIC-53 and ERGL, N-terminal carbohydrate recognition domain. ERGIC-53 and ERGL are eukaryotic mannose-binding type 1 transmembrane proteins of the early secretory pathway that transport newly synthesized glycoproteins from the endoplasmic reticulum (ER) to the ER-Golgi intermediate compartment (ERGIC). ERGIC-53 and ERGL have an N-terminal lectin-like carbohydrate recognition domain (represented by this alignment model) as well as a C-terminal transmembrane domain. ERGIC-53 functions as a 'cargo receptor' to facilitate the export of glycoproteins with different characteristics from the ER, while the ERGIC-53-like protein (ERGL) which may act as a regulator of ERGIC-53. In mammals, ERGIC-53 forms a complex with MCFD2 (multi-coagulation factor deficiency 2) which then recruits blood coagulation factors V and VIII. Mutations in either MCFD2 or ERGIC-53 cause a mild form of inherited hemophilia known as combined deficiency of factors V and VIII (F5F8D). In addition to the lectin and transmembrane domains, ERGIC-53 and ERGL have a short N-terminal cytoplasmic region of about 12 amino acids. ERGIC-53 forms disulphide-linked homodimers and homohexamers. ERGIC-53 and ERGL are sequence-similar to the lectins of leguminous plants. L-type lectins have a dome-shaped beta-barrel carbohydrate recognition domain with a curved seven-stranded beta-sheet referred to as the "front face" and a flat six-stranded beta-sheet referred to as the "back face". This domain homodimerizes so that adjacent back sheets form a contiguous 12-stranded sheet and homotetramers occur by a back-to-back association of these homodimers. Though L-type lectins exhibit both sequence and structural similarity to one another, their carbohydrate binding specificities differ widely.

 44-269 1.17e-127

Legume-like lectin family; Lectins are structurally diverse proteins that bind to specific carbohydrates. This family includes the VIP36 and ERGIC-53 lectins. These two proteins were the first recognized members of a family of animal lectins similar (19-24%) to the leguminous plant lectins. The alignment for this family aligns residues lying towards the N-terminus, where the similarity of VIP36 and ERGIC-53 is greatest. However, while Fiedler and Simons identified these proteins as a new family of animal lectins, our alignment also includes yeast sequences. ERGIC-53 is a 53kD protein, localized to the intermediate region between the endoplasmic reticulum and the Golgi apparatus (ER-Golgi-Intermediate Compartment, ERGIC). It was identified as a calcium-dependent, mannose-specific lectin. Its dysfunction has been associated with combined factors V and VIII deficiency OMIM:227300 OMIM:601567, suggesting an important and substrate-specific role for ERGIC-53 in the glycoprotein- secreting pathway.

 46-267 1.86e-77

legume-like lectins: ERGIC-53, ERGL, VIP36, VIPL, EMP46, and EMP47; The legume-like (leg-like) lectins are eukaryotic intracellular sugar transport proteins with a carbohydrate recognition domain similar to that of the legume lectins. This domain binds high-mannose-type oligosaccharides for transport from the endoplasmic reticulum to the Golgi complex. These leg-like lectins include ERGIC-53, ERGL, VIP36, VIPL, EMP46, EMP47, and the UIP5 (ULP1-interacting protein 5) precursor protein. Leg-like lectins have different intracellular distributions and dynamics in the endoplasmic reticulum-Golgi system of the secretory pathway and interact with N-glycans of glycoproteins in a calcium-dependent manner, suggesting a role in glycoprotein sorting and trafficking. L-type lectins have a dome-shaped beta-barrel carbohydrate recognition domain with a curved seven-stranded beta-sheet referred to as the "front face" and a flat six-stranded beta-sheet referred to as the "back face". This domain homodimerizes so that adjacent back sheets form a contiguous 12-stranded sheet and homotetramers occur by a back-to-back association of these homodimers. Though L-type lectins exhibit both sequence and structural similarity to one another, their carbohydrate binding specificities differ widely.

 63-267 5.79e-59

VIP36 and VIPL type 1 transmembrane proteins, lectin domain; The vesicular integral protein of 36 kDa (VIP36) is a type 1 transmembrane protein of the mammalian early secretory pathway that acts as a cargo receptor transporting high mannose type glycoproteins between the Golgi and the endoplasmic reticulum (ER). Lectins of the early secretory pathway are involved in the selective transport of newly synthesized glycoproteins from the ER to the ER-Golgi intermediate compartment (ERGIC). The most prominent cycling lectin is the mannose-binding type1 membrane protein ERGIC-53, which functions as a cargo receptor to facilitate export of glycoproteins from the ER. L-type lectins have a dome-shaped beta-barrel carbohydrate recognition domain with a curved seven-stranded beta-sheet referred to as the "front face" and a flat six-stranded beta-sheet referred to as the "back face". This domain homodimerizes so that adjacent back sheets form a contiguous 12-stranded sheet and homotetramers occur by a back-to-back association of these homodimers. Though L-type lectins exhibit both sequence and structural similarity to one another, their carbohydrate binding specificities differ widely.

legume lectins; The L-type (legume-type) lectins are a highly diverse family of carbohydrate binding proteins that generally display no enzymatic activity toward the sugars they bind. This family includes arcelin, concanavalinA, the lectin-like receptor kinases, the ERGIC-53/VIP36/EMP46 type1 transmembrane proteins, and an alpha-amylase inhibitor. L-type lectins have a dome-shaped beta-barrel carbohydrate recognition domain with a curved seven-stranded beta-sheet referred to as the "front face" and a flat six-stranded beta-sheet referred to as the "back face". This domain homodimerizes so that adjacent back sheets form a contiguous 12-stranded sheet and homotetramers occur by a back-to-back association of these homodimers. Though L-type lectins exhibit both sequence and structural similarity to one another, their carbohydrate binding specificities differ widely.

EMP46 and EMP47 type 1 transmembrane proteins, N-terminal lectin domain; EMP46 and EMP47, N-terminal carbohydrate recognition domain. EMP46 and EMP47 are fungal type-I transmembrane proteins that cycle between the endoplasmic reticulum and the golgi apparatus and are thought to function as cargo receptors that transport newly synthesized glycoproteins. EMP47 is a receptor for EMP46 responsible for the selective transport of EMP46 by forming hetero-oligomerization between the two proteins. EMP46 and EMP47 have an N-terminal lectin-like carbohydrate recognition domain (represented by this alignment model) as well as a C-terminal transmembrane domain. EMP46 and EMP47 are 45% sequence-identical to one another and have sequence homology to a class of intracellular lectins defined by ERGIC-53 and VIP36. L-type lectins have a dome-shaped beta-barrel carbohydrate recognition domain with a curved seven-stranded beta-sheet referred to as the "front face" and a flat six-stranded beta-sheet referred to as the "back face". This domain homodimerizes so that adjacent back sheets form a contiguous 12-stranded sheet and homotetramers occur by a back-to-back association of these homodimers. Though L-type lectins exhibit both sequence and structural similarity to one another, their carbohydrate binding specificities differ widely.
