FunctionDual specificity protein kinase activity catalyzing autophosphorylation and phosphorylation of exogenous substrates on both serine/threonine and tyrosine residues. Probably plays a central role at and after the meiotic phase of spermatogenesis.
Sequence similaritiesBelongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. Contains 1 protein kinase domain.
DomainThe extracatalytic C-terminal part is highly rich in proline residues.
Post-translational modificationsAutophosphorylated on serine and tyrosine residues.
