Target Species

Human

Target Name

BRSK1

Target Full Name

Serine/threonine-protein kinase BRSK1

Target Function

Serine/threonine-protein kinase that plays a key role in polarization of neurons and centrosome duplication. Phosphorylates CDC25B, CDC25C, MAPT/TAU, RIMS1, TUBG1, TUBG2 and WEE1. Following phosphorylation and activation by STK11/LKB1, acts as a key regulator of polarization of cortical neurons, probably by mediating phosphorylation of microtubule-associated proteins such as MAPT/TAU at 'Thr-529' and 'Ser-579'. Also regulates neuron polarization by mediating phosphorylation of WEE1 at 'Ser-642' in postmitotic neurons, leading to down-regulate WEE1 activity in polarized neurons. In neurons, localizes to synaptic vesicles and plays a role in neurotransmitter release, possibly by phosphorylating RIMS1. Also acts as a positive regulator of centrosome duplication by mediating phosphorylation of gamma-tubulin (TUBG1 and TUBG2) at 'Ser-131', leading to translocation of gamma-tubulin and its associated proteins to the centrosome. Involved in the UV-induced DNA damage checkpoint response, probably by inhibiting CDK1 activity through phosphorylation and activation of WEE1, and inhibition of CDC25B and CDC25C.

Target Background

Enables magnesium ion binding activity; protein serine/threonine kinase activity; and tau-protein kinase activity. Involved in mitotic G2 DNA damage checkpoint signaling and protein phosphorylation. Acts upstream of or within G2/M transition of mitotic cell cycle; peptidyl-serine phosphorylation; and response to UV. Located in cell junction; cytoplasm; and nucleoplasm.
