Protein Structure
UniProt Annotation
Function Testis-specific serine/threonine-protein kinase required during spermatid development. Phosphorylates 'Ser-281' of TSKS and SPAG16. 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:18367677, ECO:0000269PubMed:18533145, ECO:0000269PubMed:20053632, ECO:0000269PubMed:9412477}.
Subcellular Localization Cytoplasm. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole. Cytoplasmic vesicle, secretory vesicle, acrosome. Note=Present in the cytoplasm of elongating spermatids. In spermatozoa, localizes in the equatorial segment, neck, the midpiece and in a specific sperm head compartment. In spermatids, concentrates in centrioles during flagellogenesis. Localizes in the tail and acrosomal regions of epididymal sperm.
Disease Associations
Tissue Specificity Testis-specific. Expressed only in the spermatids postmeiotically 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. Also present in the epididymal sperm (at protein level). {ECO:0000269PubMed:18533145, ECO:0000269PubMed:20729278, ECO:0000269PubMed:9412477, ECO:0000269PubMed:9651519}.
