機能Testis-specific serine/threonine-protein kinase required during spermatid development. Phosphorylates 'Ser-288' of TSKS. Involved in the late stages of spermatogenesis, during the reconstruction of the cytoplasm. During spermatogenesis, required for the transformation of a ring-shaped structure around the base of the flagellum originating from the chromatoid body.
組織特異性Testis-specific. Present in sperm (at protein level).
配列類似性Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. Contains 1 protein kinase domain.
細胞内局在Cytoplasm. Cytoplasmic vesicle > secretory vesicle > acrosome. Cell projection > cilium > flagellum. In spermatozoa, present in the sperm head and in the flagellum.
