Function

M4K4_HUMAN Serine/threonine kinase that may play a role in the response to environmental stress and cytokines such as TNF-alpha. Appears to act upstream of the JUN N-terminal pathway. Phosphorylates SMAD1 on Thr-322.^[1] ^[2]

Publication Abstract from PubMed

By virtue of its role in cellular proliferation, microtubule-associated serine/threonine kinase-like (MASTL) represents a novel target and a first-in-class (FIC) opportunity to provide a new impactful therapeutic agent to oncology patients. Herein, we describe a hit-to-lead optimization effort that resulted in the delivery of two highly selective MASTL inhibitors. Key strategies leveraged to enable this work included structure-based drug design (SBDD), analysis of lipophilic efficiency (LipE) and novel synthesis. The resulting advanced lead compounds enabled a tumor growth inhibition study which was pivotal in assessing the potential value of MASTL as an oncology therapeutic target.
