Lemur Tyrosine Kinase 3 (LMTK3)

Target
LMTK3
Molecular classification
Serine/threonine kinase, Enzyme
01

Overview

Lemur tyrosine kinase 3 (LMTK3) is a protein kinase primarily functioning as a serine/threonine kinase. It is involved in gene regulation, protein trafficking, and oncogenesis. Overexpression is linked to several cancers, including breast, glioblastoma, and lung cancers. It also plays a role in central nervous system function, with knockout mice showing hyperactivity and cognitive impairments. The small molecule inhibitor C28 demonstrates anti-cancer activity by disrupting LMTK3's interaction with HSP90.
