The protein encoded by this gene is an atypical member of the family of growth factor receptor protein tyrosine kinases, differing from other members at a number of conserved residues in the activation and nucleotide binding domains. This gene product belongs to a subfamily whose members do not appear to be regulated by phosphorylation in the activation segment. It has been suggested that mediation of biological activity by recruitment of a signaling-competent auxiliary protein may occur through an as yet uncharacterized mechanism. Two alternative splice variants have been identified, encoding distinct isoforms.[5]

History

edit

The gene encoding mouse RYK was first identified in 1992.[6] Subsequently, cDNA encoding the RYK protein have been isolated from the following species.[7]

Structure

edit

In common with other receptor tyrosine kinase family members, RYK is composed of three domains, an N-terminal, extracellular ligand-binding domain, a transmembrane spanning domain and a C-terminal intracellular domain. However, in contrast to other receptor tyrosine kinases the C-terminal domain of RYK is devoid of detectable kinase activity.[7]

Function

edit

RYK is involved in regulation of axon growth during development of the nervous system.[8]
