Research Backgrounds
Serine/threonine-protein kinase, which may play a role in the response to environmental stress. Appears to act upstream of the JUN N-terminal pathway. May play a role in hematopoietic lineage decisions and growth regulation. Able to autophosphorylate. Together with CLNK, it enhances CD3-triggered activation of T-cells and subsequent IL2 production (By similarity).
Autophosphorylates: phosphorylation promotes ubiquitination by the Cul7-RING(FBXW8) ubiquitin-protein ligase complex, leading to its degradation by the proteasome.
Tyrosine-phosphorylated after activation of hemopoietic cells.
Ubiquitinated by the Cul7-RING(FBXW8) ubiquitin-protein ligase complex following autophosphorylation, leading to its degradation by the proteasome.
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.
Interacts with MAP3K1. Interacts with FBXW8. Interacts with CLNK (via its SH2 domain) (By similarity).
Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily.
