RT sensor domains.";

CC -!- FUNCTION: Plays a role in phosphate homeostasis. Mediates phosphate
CC export from the cell (PubMed:23791524, PubMed:25938945). Binds inositol
CC hexakisphosphate (Ins6P) and similar inositol polyphosphates, such as
CC 5-diphospho-inositol pentakisphosphate (5-InsP7); these are important
CC intracellular signaling molecules (PubMed:27080106).
CC {ECO:0000250|UniProtKB:Q9Z0U0, ECO:0000269|PubMed:23791524,
CC ECO:0000269|PubMed:25938945, ECO:0000269|PubMed:27080106}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:23791524};
CC Multi-pass membrane protein {ECO:0000305}.

CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9UBH6-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9UBH6-2; Sequence=VSP_030748;
CC -!- TISSUE SPECIFICITY: Widely expressed. Detected in spleen, lymph node,
CC thymus, leukocytes, bone marrow, heart, kidney, pancreas and skeletal
CC muscle. {ECO:0000269|PubMed:9927670, ECO:0000269|PubMed:9990033}.
CC -!- DEVELOPMENTAL STAGE: Expressed in fetal liver.
CC {ECO:0000269|PubMed:9927670, ECO:0000269|PubMed:9990033}.
CC -!- DOMAIN: The SPX domain has high affinity for inositol polyphosphates,
CC such as myo-inositol hexakisphosphate and 5-diphospho-myo-inositol
CC pentakisphosphate (5-InsP7). Its affinity for inorganic phosphate is
CC tow to three orders of magnitude lower. {ECO:0000269|PubMed:27080106}.
CC -!- DISEASE: Basal ganglia calcification, idiopathic, 6 (IBGC6)
CC [MIM:616413]: A form of basal ganglia calcification, an autosomal
CC dominant condition characterized by symmetric calcification in the
CC basal ganglia and other brain regions. Affected individuals can either
CC be asymptomatic or show a wide spectrum of neuropsychiatric symptoms,
CC including parkinsonism, dystonia, tremor, ataxia, dementia, psychosis,
CC seizures, and chronic headache. Serum levels of calcium, phosphate,
CC alkaline phosphatase and parathyroid hormone are normal. The
CC neuropathological hallmark of the disease is vascular and pericapillary
CC calcification, mainly of calcium phosphate, in the affected brain
CC areas. {ECO:0000269|PubMed:25938945}. Note=The disease is caused by
CC variants affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the SYG1 (TC 2.A.94) family. {ECO:0000305}.
CC -!- CAUTION: It is unclear whether its ability to act as a receptor for
CC xenotropic and polytropic murine leukemia retroviruses is relevant in
CC vivo and whether such viruses can infect human. {ECO:0000305}.
