a protein kinase of the STE20 family. Expressed primarily in hematopoietic organs, including bone marrow, spleen and thymus. Also expressed at very low levels in lung, kidney, mammary glands and small intestine. May play a role in hematopoietic lineage decisions and growth regulation. Positively regulated by PGE2 and a negative regulator of PGE2-induced FOS gene transcription. Note: This description may include information from UniProtKB.
