E3 ubiquitin-protein transferase MAEA isoform X2 [Homo sapiens]

Protein Classification

E3 ubiquitin-protein transferase MAEA( domain architecture ID 12218107)

E3 ubiquitin-protein transferase MAEA is a core component of the CTLH E3 ubiquitin-protein ligase complex that selectively accepts ubiquitin from UBE2H and mediates ubiquitination and subsequent proteasomal degradation of the transcription factor HBP1

 159-300 9.97e-54

CTLH/CRA C-terminal to LisH motif domain; RanBPM is a scaffolding protein and is important in regulating cellular function in both the immune system and the nervous system. This domain is at the C-terminus of the proteins and is the binding domain for the CRA motif (for CT11-RanBPM), which is comprised of approximately 100 amino acids at the C terminal of RanBPM. It was found to be important for the interaction of RanBPM with fragile X mental retardation protein (FMRP), but its functional significance has yet to be determined. This region contains CTLH and CRA domains annotated by SMART; however, these may be a single domain, and it is refereed to as a C-terminal to LisH motif.

 335-364 1.49e-16

U-box domain, a modified RING finger, found in erythroblast macrophage protein (Emp) and similar proteins; Emp, also known as cell proliferation-inducing gene 5 protein or macrophage erythroblast attacher (MAEA), is a key protein which functions in normal differentiation of erythroid cells and macrophages. It is a potential biomarker for hematopoietic evaluation of Hematopoietic stem cell transplantation (HSCT) patients. Emp was initially identified as a heparin-binding protein involved in the association of erythroblasts with macrophages. It promotes erythroid proliferation and maturation. It also plays an important role in erythroblastic island formation. Absence of Emp leads to failure of erythroblast nuclear extrusion. It is required in definitive erythropoiesis and plays a cell intrinsic role in the erythroid lineage. Emp contains a Lissencephaly type-1-like homology (LisH) motif, a C-terminal to LisH (CTLH) domain, and a RING-like U-box domain at the C-terminus.

It is suggested that LisH motifs contribute to the regulation of microtubule dynamics, either by mediating dimerisation, or else by binding cytoplasmic dynein heavy chain or microtubules directly.

 337-364 1.04e-03

U-box domain, a modified RING finger; The U-box protein family is a family of E3 enzymes that also includes the HECT family and the RING finger family. The E3 enzyme is ubiquitin-protein ligase that cooperates with a ubiquitin-activating enzyme (E1) and a ubiquitin-conjugating enzyme (E2), and plays a central role in determining the specificity of the ubiquitination system. It removes the ubiquitin molecule from the E2 enzyme and attaches it to the target substrate, forming a covalent bond between ubiquitin and the target. U-box proteins are characterized by the presence of a U-box domain of approximately 70 amino acids. The U-box is a modified form of the RING finger domain that lacks metal chelating cysteines and histidines. It resembles the cross-brace RING structure consisting of three beta-sheets and a single alpha-helix, which would be stabilized by salt bridges instead of chelated metal ions. U-box proteins are widely distributed among eukaryotic organisms and show a higher prevalence in plants than in other organisms.

 338-360 8.45e-03

Degenerated RING (dRING) finger found in Saccharomyces cerevisiae required for meiotic nuclear division protein 5 (Rmd5p) and similar proteins; Rmd5p, also known as glucose-induced degradation protein 2 (Gid2) or sporulation protein RMD5, is an E3 ubiquitin ligase containing a Lissencephaly type-1-like homology motif (LisH), a C-terminal to LisH motif (CTLH) domain, and a degenerated RING finger that is characterized by lacking the second, fifth, and sixth Zn2+ ion-coordinating residues compared with the classic C3H2C3-/C3HC4-type RING fingers. It forms the heterodimeric E3 ligase unit of the glucose induced degradation deficient (GID) complex with Gid9 (also known as Fyv10), which has a degenerated RING finger as well. The GID complex triggers polyubiquitylation and subsequent proteasomal degradation of the gluconeogenic enzymes fructose-1, 6-bisphosphate by fructose-1, 6-bisphosphatase (FBPase), phosphoenolpyruvate carboxykinase (PEPCK), and cytoplasmic malate dehydrogenase (c-MDH). Moreover, Rmd5p can form the GID complex with the other six Gid proteins, including Gid1/Vid30, Gid4/Vid24, Gid5/Vid28, Gid7, Gid8, and Gid9/Fyv10. The GID complex in which the seven Gid proteins reside functions as a novel ubiquitin ligase (E3) involved in the regulation of carbohydrate metabolism.
