CC -!- FUNCTION: Auxiliary component of the CatSper complex, a complex
CC involved in sperm cell hyperactivation. Sperm cell hyperactivation is
CC needed for sperm motility which is essential late in the preparation of
CC sperm for fertilization. {ECO:0000250|UniProtKB:A2RTF1}.
CC -!- SUBUNIT: Component of the CatSper complex or CatSpermasome composed of
CC the core pore-forming members CATSPER1, CATSPER2, CATSPER3 and CATSPER4
CC as well as auxiliary members CATSPERB, CATSPERG, CATSPERD, CATSPERE,
CC CATSPERZ, C2CD6/CATSPERT, TMEM249, TMEM262 and EFCAB9. HSPA1 may be an
CC additional auxiliary complex member. The core complex members CATSPER1,
CC CATSPER2, CATSPER3 and CATSPER4 form a heterotetrameric channel. The
CC auxiliary CATSPERB, CATSPERG, CATSPERD and CATSPERE subunits form a
CC pavilion-like structure over the pore which stabilizes the complex
CC through interactions with CATSPER4, CATSPER3, CATSPER1 and CATSPER2
CC respectively. TMEM262/CATSPERH interacts with CATSPERB, further
CC stabilizing the complex. C2CD6/CATSPERT interacts at least with
CC CATSPERD and is required for targeting the CatSper complex in the
CC flagellar membrane. {ECO:0000250|UniProtKB:A2RTF1}.
CC -!- SUBCELLULAR LOCATION: Cell projection, cilium, flagellum membrane
CC {ECO:0000250|UniProtKB:A2RTF1}; Single-pass membrane protein
CC {ECO:0000250|UniProtKB:A2RTF1}. Note=Predominantly located in the
CC principal piece of the sperm tail. {ECO:0000250|UniProtKB:A2RTF1}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9H7T0-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9H7T0-2; Sequence=VSP_027008;
CC -!- CAUTION: In mouse, Slco6c1 is an additional auxiliary subunit of the
CC CatSper complex. It is unclear if the related SLCO6A1 protein performs
CC the same role in non-rodent species. {ECO:0000305}.
