Kinase Classification: Group PKL: Family Alpha: Subfamily AlphaK1

Domain Structure

Members have an extended N-terminal region followed by an alpha kinase domain.

Evolution

AlphaK1 (ALPK1) is a single-copy gene in vertebrates. Clear orthologs have also been detected in the chordate Branchiostoma floridae (lancelet) and the sea anemone, Nematostella, suggesting that the gene was born in early metazoan evolution, but then lost from many lineages.

Functions

ALPK1 has been implicated in vesicle transport from the Golgi to the plasma membrane [1], perhaps by myosin phosphorylation. Mouse ALPK1 mutants were associated with motor co-ordination defects [2], and the gene has been associated with both gout and kidney disease. Human ALPK1 has also been shown to be a receptor for the bacterial ADP-heptose[3]. ADP-heptose binding causes ALPK1 to phosphorylate TIFA and activate NFkB signaling.
