OX NCBI_TaxID=8364;
RN [1]
RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC STRAIN=N6; TISSUE=Skeletal muscle, and Tadpole;
RG NIH - Xenopus Gene Collection (XGC) project;
RL Submitted (NOV-2003) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Monovalent cation channel required for maintenance of rapid
CC intracellular calcium release. May act as a potassium counter-ion
CC channel that functions in synchronization with calcium release from
CC intracellular stores. {ECO:0000250|UniProtKB:Q3TMP8}.
CC -!- SUBUNIT: Homotrimer; trimerization probably requires binding to
CC phosphatidylinositol 4,5-bisphosphate (PIP2).
CC {ECO:0000250|UniProtKB:A5A6S6, ECO:0000250|UniProtKB:Q9NA73}.
CC -!- SUBCELLULAR LOCATION: Sarcoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:A5A6S6}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:A5A6S6}. Nucleus membrane
CC {ECO:0000250|UniProtKB:A5A6S6}.
CC -!- SIMILARITY: Belongs to the TMEM38 family. {ECO:0000305}.
