Protein Structure
UniProt Annotation
Function Testis-specific serine/threonine-protein kinase required during spermatid development. Phosphorylates 'Ser-281' 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. {ECO:0000269PubMed:20053632}.
Subcellular Localization Cytoplasm. Cytoplasmic vesicle, secretory vesicle, acrosome. Cell projection, cilium, flagellum. Note=In spermatozoa, present in the sperm head and in the flagellum.
Disease Associations
Tissue Specificity Testis-specific. Expressed only in postmeiotic spermatids at the final stages of cytodifferentiation in the seminiferous tubules (at protein level). Not detected in released sperms in the lumen of the seminiferous tubules and the epididymis. {ECO:0000269PubMed:20729278, ECO:0000269PubMed:9412477, ECO:0000269PubMed:9651519}.
