CC   -!- FUNCTION: Ca(2+) release-activated Ca(2+) (CRAC) channel subunit which
CC       mediates Ca(2+) influx following depletion of intracellular Ca(2+)
CC       stores and channel activation by the Ca(2+) sensor, STIM1
CC       (PubMed:16582901, PubMed:16645049, PubMed:16733527, PubMed:16766533,
CC       PubMed:16807233, PubMed:19249086, PubMed:23307288, PubMed:24351972,
CC       PubMed:24591628, PubMed:28219928, PubMed:20354224, PubMed:26956484).
CC       CRAC channels are the main pathway for Ca(2+) influx in T-cells and
CC       promote the immune response to pathogens by activating the
CC       transcription factor NFAT (PubMed:16582901). Plays a prominent role in
CC       Ca(2+) influx at the basolateral membrane of mammary epithelial cells
CC       independently of the Ca(2+) content of endoplasmic reticulum or Golgi
CC       stores. May mediate transepithelial transport of large quantities of
CC       Ca(2+) for milk secretion. {ECO:0000250|UniProtKB:Q8BWG9,

CC   -!- ACTIVITY REGULATION: Oxidation at Cys-195 leads to inactivation of
CC       channel activity. {ECO:0000269|PubMed:20354224,
CC       ECO:0000269|PubMed:28219928}.
CC   -!- SUBUNIT: Interacts with STIM1 and STIM2; this regulates channel
CC       activity (PubMed:17905723, PubMed:19249086, PubMed:24351972,
CC       PubMed:28219928, PubMed:27185316, PubMed:30481768). Interacts with
CC       CALM; this may displace STIM1 and STIM2 and might thereby modulate
CC       channel activity (PubMed:23109337). Interacts with CRACR2A/EFCAB4B; the
CC       interaction is direct and takes place in absence of Ca(2+)
CC       (PubMed:20418871). Forms a complex with CRACR2A/EFCAB4B and STIM1 at
CC       low concentration of Ca(2+), the complex dissociates at elevated Ca(2+)
CC       concentrations. Interacts with ASPH (isoform 8) (PubMed:22586105).
CC       Interacts with SLC35G1 (PubMed:22084111). Interacts with UBQLN1
CC       (PubMed:23307288). Interacts with ADCY8; interaction is calcium store
CC       depletion independent; interaction occurs in membrane raft; interaction
CC       increases markedly after store depletion; positively regulates SOCE-
CC       induced adenylate cyclase activity; contributes to the targeting of
CC       ADCY8 to discrete regions of the plasma membrane that are shielded from
CC       other calcium events (PubMed:22494970). Interacts with EFHB; the
CC       interaction takes place upon Ca(2+)-store depletion (PubMed:30481768).
CC       Interacts (via N- and C-termini) with ATP2C2 (via N-terminus); this
CC       interaction regulates Ca(2+) influx at the plasma membrane.

CC       cytokines, and normal lymphocytes counts and serum immunoglobulin
CC       levels. In surviving patients ectodermal dysplasia with anhidrosis and

CC       Tubular aggregates in muscle are structures of variable appearance
CC       consisting of an outer tubule containing either one or more
