Summary: Enables protein serine/threonine kinase activity. Involved in several processes, including G2/M transition of mitotic cell cycle; mitotic morphogenesis checkpoint signaling; and protein localization to septin ring. Located in cellular bud neck septin ring. Orthologous to human BRSK1 (BR serine/threonine kinase 1) and BRSK2 (BR serine/threonine kinase 2). [provided by Alliance of Genome Resources, Nov 2024]

Preferred Names: protein kinase HSL1

NP_012821.2

EC 2.7.11.1

Nim1p-related protein kinase; septin-binding kinase that localizes to the bud neck septin ring and regulates the morphogenesis checkpoint; phosphorylates Hsl7p and cooperates with Elm1p to recruit Hsl7p to the mother-bud neck, as a prerequisite for the subsequent recruitment, phosphorylation, and degradation of Swe1p; autophosphorylation enhances interactions with Hsl7p
