About LMTK2

Cytogenetic location: 7q21.3 Genomic coordinates (GRCh38): 7:98,106,862-98,209,638 (from NCBI)

This gene has 2 transcripts (splice variants), 198 orthologues and 53 paralogues. Ubiquitous expression in brain (RPKM 11.9), colon (RPKM 7.7) and 25 other tissues.

Summary

The protein encoded by this gene belongs to the protein kinase superfamily and the protein tyrosine kinase family. It contains N-terminal transmembrane helices and a long C-terminal cytoplasmic tail with serine/threonine/tyrosine kinase activity. This protein interacts with several Other proteins, such as Inhibitor-2 (Inh2), protein phosphatase-1 (PP1C), p35, and Myosin VI. It phosporylates Other proteins, and is itself also phosporylated when interacting with cyclin-dependent kinase 5 (CDK5)/p35 complex. This protein involves in nerve growth factor (NGF)-TrkA signalling, and also plays a critical role in endosomal membrane trafficking. Mouse studies suggested an essential role of this protein in spermatogenesis. [provided by RefSeq, Oct 2009]
