CC -!- FUNCTION: Required for correct axoneme development in spermatozoa.
CC Important for normal development of the manchette and sperm head
CC morphology. Essential for male fertility. Plays a role in localization
CC of the intraflagellar transport protein IFT20 to the manchette,
CC suggesting function as an adapter for dynein-mediated protein transport
CC during spermatogenesis. Also plays a role in bone growth where it seems
CC to be required for normal osteoblast differentiation.
CC {ECO:0000250|UniProtKB:Q8C9J3}.
CC -!- SUBUNIT: Interacts (via C-terminus) with IFT20. Interacts with DYNC1I2.
CC {ECO:0000250|UniProtKB:Q8C9J3}.
CC -!- SUBCELLULAR LOCATION: Cell projection, cilium, flagellum
CC {ECO:0000250|UniProtKB:Q9C093}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q8C9J3}. Golgi apparatus
CC {ECO:0000250|UniProtKB:Q8C9J3}. Note=Shows dynamic localization in
CC developing spermatozoa. Localizes to the manchette in step 10-12
CC elongating spermatids. Detected in the basal body and neck area of step
CC 13-14 spermatids. Localizes to the midpiece of the sperm tail in step
CC 15-16 spermatids. During the epididymal transport of spermatozoa,
CC expression in the sperm tail reduces and becomes concentrated at the
CC distal part of the midpiece. Detected in the Golgi apparatus of late
CC spermatocytes and round spermatids. Detected in the cytoplasm of
CC Sertoli cells. {ECO:0000250|UniProtKB:Q8C9J3}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1;
CC IsoId=Q9R095-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9R095-2; Sequence=VSP_027530;
CC Name=3;
CC IsoId=Q9R095-3; Sequence=VSP_027531, VSP_027532;
CC -!- TISSUE SPECIFICITY: Predominantly expressed in ciliated tissues such as
CC lung, trachea, testis, brain, and at lower levels in kidney and spleen.
CC {ECO:0000269|PubMed:10100999}.
CC -!- DEVELOPMENTAL STAGE: Expressed during the process of ciliated cell
CC differentiation. In seminiferous tubules of the testis, its expression
CC is stage-specific and is highest in spermatocytes and round spermatids.
CC {ECO:0000269|PubMed:10100999}.
