Schizosaccharomyces pombe      STE/STE20


※ STE20 family introduction

    STE20 was first identified as a putative MAP4K in mating pathway in yeast and its homologs in human constitute a large family in STE group. STE20 can further be classified into two subclasses, PAK and GCK. Structure analysis shows that the kinase domains in PAKs are located at C-terminal while GCKs kinase domains are located in N-terminal. Three mammalian STE20-like kinases have been reported to be able to phosphorylate MAP3Ks, including HPK1, GLK and PAK2. HPK1 predominantly mediate the activation of the stress-activated SAPK/JNK pathway. PAK2 is activated via binding of the Rac1 or Cdc42 and subsequently involved in direct phosphorylation of MAP3K Raf-1. Besides as a upstream activator of MAPK pathway, STE20 are often used in signaling events, including cell apoptosis, morphogenesis and cytoskeletal rearrangement such as cell motility and cell shape changes (1).
