CBL proto-oncogene N-terminal domain 1
Cbl is an adaptor protein that binds EGF receptors (or other tyrosine kinases) and SH3 domains, functioning as a negative regulator of many signaling pathways. The N-terminal domain is evolutionarily conserved, and is known to bind to phosphorylated tyrosine residues. Cbl_N is comprised of 3 structural domains of which this is the first - a four helix bundle.
