CSK

Chloroplast sensor kinase, chloroplastic

611 amino acids

Sensor kinase required for sensing the plastoquinone redox state involved in both photosystems stoichiometry adjustment (e.g. long-term adaptation via transcriptional regulation of reaction center genes of photosystems I and II) and state transitions (e.g. short-term adaptation involving reversible post-translational phosphorylation of light-harvesting complex II, LHC II), thus linking photosynthesis with gene expression in chloroplasts (PubMed:18632566, PubMed:22039472). Probably phosphorylates SIGA/SIG1 in response to plastoquinone redox state modification (PubMed:23754813).

Belongs to the chloroplast sensor kinase protein family.

CSK

Tyrosine-protein kinase CSK

450 amino acids

Non-receptor tyrosine-protein kinase that plays an important role in the regulation of cell growth, differentiation, migration and immune response. Phosphorylates tyrosine residues located in the C-terminal tails of Src-family kinases (SFKs) including LCK, SRC, HCK, FYN, LYN, CSK or YES1. Upon tail phosphorylation, Src-family members engage in intramolecular interactions between the phosphotyrosine tail and the SH2 domain that result in an inactive conformation. To inhibit SFKs, CSK is recruited to the plasma membrane via binding to transmembrane proteins or adapter proteins located near the plasma membrane. Suppresses signaling by various surface receptors, including T-cell receptor (TCR) and B-cell receptor (BCR) by phosphorylating and maintaining inactive several positive effectors such as FYN or LCK (By similarity).

Belongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily.
