Protein

E3 ubiquitin-protein ligase CBL-C

Gene

CBLC

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acts as an E3 ubiquitin-protein ligase, which accepts ubiquitin from specific E2 ubiquitin-conjugating enzymes, and then transfers it to substrates promoting their degradation by the proteasome. Functionally coupled with the E2 ubiquitin-protein ligases UB2D1, UB2D2 and UB2D3. Regulator of EGFR mediated signal transduction; upon EGF activation, ubiquitinates EGFR. Isoform 1, but not isoform 2, inhibits EGF stimulated MAPK1 activation. Promotes ubiquitination of SRC phosphorylated at 'Tyr-419'. In collaboration with CD2AP may act as regulatory checkpoint for Ret signaling by modulating the rate of RET degradation after ligand activation; CD2AP converts it from an inhibitor to a promoter of RET degradation; the function limits the potency of GDNF on neuronal survival.5 Publications

Miscellaneous

This protein has one functional calcium-binding site.

Interactioni

Subunit structurei

Interacts with ubiquitin-conjugating enzyme E2 UBE2D2 and UBE2D3. Isoform 1 interacts with EGFR (tyrosine phosphorylated). Interacts with the SH3 domain proteins LYN and CRK. Interacts (via RING-type zinc finger) with TGFB1I1 (via LIM zinc-binding domain 2); the interaction is direct and enhances the E3 activity. Interacts directly with RET (inactive) and CD2AP; dissociates from RET upon RET activation by GDNF which also increases the interaction with CD2AP suggesting dissociation as CBLC:CD2AP complex. Interacts with SRC; the interaction is enhanced when SRC is phosphorylated at 'Tyr-419'.7 Publications

Domaini

EF-hand-like and Sh2-like domains are required for N-terminal inhibition of E3 activity.1 Publication
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.PROSITE-ProRule annotation1 Publication
