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. Required for a distribution of the CatSper
CC complex in linear quadrilateral nanodomains along the flagellum,
CC maximizing fertilization inside the mammalian female reproductive
CC tract. Together with EFCAB9, associates with the CatSper channel pore
CC and is required for the two-row structure of each single CatSper
CC channel. {ECO:0000250|UniProtKB:Q9CQP8}.
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 (By similarity).
CC HSPA1 may be an additional auxiliary complex member (By similarity).
CC The core complex members CATSPER1, CATSPER2, CATSPER3 and CATSPER4 form
CC a heterotetrameric channel (By similarity). The auxiliary CATSPERB,
CC CATSPERG, CATSPERD and CATSPERE subunits form a pavilion-like structure
CC over the pore which stabilizes the complex through interactions with
CC CATSPER4, CATSPER3, CATSPER1 and CATSPER2 respectively (By similarity).
CC TMEM262/CATSPERH interacts with CATSPERB, further stabilizing the
CC complex. C2CD6/CATSPERT interacts at least with CATSPERD and is
CC required for targeting the CatSper complex in the flagellar membrane
CC (By similarity). Interacts with EFCAB9; the interaction is direct,
CC Ca(2+)-dependent and connects EFCAB9 with the CatSper complex (By
CC similarity). Dissociates from EFCAB9 at elevated pH (By similarity).
CC {ECO:0000250|UniProtKB:Q91ZR5, ECO:0000250|UniProtKB:Q9CQP8}.
CC -!- SUBCELLULAR LOCATION: Cell projection, cilium, flagellum membrane
CC {ECO:0000269|PubMed:28226241}; Peripheral membrane protein
CC {ECO:0000305}. Note=Specifically located in the principal piece of
CC sperm tail (PubMed:28226241). Although it does not contain a
CC transmembrane domain, localizes with the CatSper complex at the
CC flagellum membrane (PubMed:28226241). {ECO:0000269|PubMed:28226241}.
CC -!- CAUTION: A report observed N-glycosylation at Asn-58 (PubMed:19139490).
CC However, as the protein is not predicted to localize in an
CC extracellular compartment of the cell, additional evidence is required
CC to confirm this result. {ECO:0000305|PubMed:19139490}.
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}.
