Serine/threonine-protein kinase LMTK2 also known as Lemur tyrosine kinase 2 (LMTK2) is an enzyme that in humans is encoded by the LMTK2 gene. [5] [6]
The LMTK2 enzyme belongs to both the protein kinase and the tyrosine kinase families. It contains N-terminus transmembrane helices and a long C-terminal cytoplasmic tail with serine/threonine kinase activity. This protein interacts with several other proteins, such as androgen receptor, inhibitor-2 (Inh2), protein phosphatase-1 (PP1C), p35, and myosin VI. It phosphorylates other proteins, and is itself also phosphorylated when interacting with cyclin-dependent kinase 5 (cdk5)/p35 complex. This protein is involved 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. [6]
Loss of LMTK2 has been implicated to play a role in development of prostate cancer. [7]
LMTK2 has been shown to interact with PPP1CA, [8] Cyclin-dependent kinase 5 [9] and PPP1R2. [8]
