Summary: Enables protein serine/threonine kinase activity. Involved in several processes, including negative regulation of macromolecule biosynthetic process; negative regulation of sterol import; and positive regulation of protein import into nucleus. Located in cellular bud; fungal-type vacuole; and nucleus. Human ortholog(s) of this gene implicated in clear cell renal cell carcinoma. Orthologous to several human genes including BUB1B-PAK6 (BUB1B-PAK6 readthrough) and PAK6 (p21 (RAC1) activated kinase 6). [provided by Alliance of Genome Resources, Nov 2024]

Cla4 phosphorylates histone methyltransferase Set1 to prevent its degradation by the APC/C[Cdh1] complex.

Cla4p Kinase Activity Is Down-Regulated by Fus3p during Yeast Mating.

Upon arrival at the bud cortex, Vac17 is phosphorylated by Cla4. Cla4-dependent phosphorylation is required for the ubiquitylation and subsequent degradation of Vac17 and the release of the vacuole from Myo2.
Title: Spatial regulation of organelle release from myosin V transport by p21-activated kinases.
Results suggest that the Cdc42 effectors Ste20, Cla4, and Skm1 translocate into the nucleus, where they modulate expression of sterol uptake genes via Sut1, thereby controlling sterol homeostasis.
Title: The Cdc42 effectors Ste20, Cla4, and Skm1 down-regulate the expression of genes involved in sterol uptake by a mitogen-activated protein kinase-independent pathway.
Ste20p & Cla4p may function as negative modulators of sterol biosynthesis. Cla4p has negative effect on steryl ester formation. Ste20p and Cla4p may regulate cell polarity in part through the modulation of sterol homeostasis.

polarisome components and Cla4p are required for the initial assembly of the septin ring
Title: Septin ring assembly requires concerted action of polarisome components, a PAK kinase Cla4p, and the actin cytoskeleton in Saccharomyces cerevisiae.
Our findings suggest that Cla4-dependent phosphorylation promotes the initial association of Lte1 with Ras at the bud cortex and that Ras is required to stabilize phosphorylated forms of Lte1 at the bud cortex.
Title: Ras and the Rho effector Cla4 collaborate to target and anchor Lte1 at the bud cortex.
