Protein

E3 ubiquitin-protein ligase CBL-B-A

Gene
cblb-a
Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

E3 ubiquitin-protein ligase which accepts ubiquitin from specific E2 ubiquitin-conjugating enzymes, and transfers it to substrates, generally promoting their degradation by the proteasome By similarity.

Domaini

The N-terminus is composed of the phosphotyrosine binding (PTB) domain, a short linker region and the RING-type zinc finger. The PTB domain, which is also called TKB (tyrosine kinase binding) domain, is composed of three different subdomains: a four-helix bundle (4H), a calcium-binding EF hand and a divergent SH2 domain.
The RING-type zinc finger domain mediates binding to an E2 ubiquitin-conjugating enzyme By similarity.
