Cbl adaptor proteins are RING-type E3 ubiquitin ligases. Cbl may be involved in the negative regulation of thymocyte development, targeting its substrate for ubiquitination [PubMed11864842]. The ubiquitin ligase activity of Cbl, and of its homologue Cbl-b, plays a role in the negative regulation of upstream kinases, such as Lck, Syk and PI3K, in T and B cells [PubMed12787751]. Cbl can interact with the EGF receptor (EGFR), causing the ubiquitination of the receptor following EGF ligand binding and Grb2 association. Ubiquitination is required for ligand-induced endocytosis of the EGFR [PubMed15194809].

The N-terminal region is composed of three evolutionarily conserved domains: an N-terminal four-helix bundle domain, an EF Hand-like domain and a SH2-like domain, which together are known to bind to phosphorylated tyrosine residues. This entry represents the N-terminal four-helical bundle domain.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.

Alignments of sequences to 3 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have different domain combinations including a N-terminal domain of cbl (N-cbl) domain.

Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.

Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 3 hidden Markov models representing the N-terminal domain of cbl (N-cbl) superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
