Summary: Predicted to enable protein serine/threonine kinase activity. Involved in several processes, including embryonic body morphogenesis; positive regulation of GTPase activity; and positive regulation of endocytic recycling. Located in cytoplasm. Is expressed in Ea and Ep. Used to study cerebral cavernous malformation. Orthologous to several human genes including CDC42BPA (CDC42 binding protein kinase alpha) and CDC42BPB (CDC42 binding protein kinase beta). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

MRCK-1 is required for activation of contractile actomyosin dynamics and elevated cortical tension in the apical cell cortex of endoderm precursor cells. MRCK-1 is apically localized by active Cdc42 at the external, cell-cell contact-free surfaces of apically constricting cells, downstream of cell fate determination mechanisms.

Data show that combined loss of ROCK and PAK, or ROCK and MRCK, completely prevented embryonic elongation, but a constitutively active form of MLC-4 could only rescue a lack of MRCK.
