RNA EXPRESSION OVERVIEW
RNA cell line category: Expressed in all Organ Origin Category Expression Alphabetical Cell lines sorted after organ of phenotypic resemblance. Cell lines sorted after biological source for establishment. Cell lines sorted after the cell line category according to Cellosaurus. Cell lines sorted on descending RNA expression. Cell lines sorted alphabetically.

GENE INFORMATION
Gene name	TPCN1 (HGNC Symbol)
Synonyms	FLJ20612, KIAA1169, TPC1
Description	Two pore segment channel 1 (HGNC Symbol)
Entrez gene summary	Voltage-gated Ca(2+) and Na+ channels have 4 homologous domains, each containing 6 transmembrane segments, S1 to S6. TPCN1 is similar to these channels, but it has only 2 domains containing S1 to S6 (Ishibashi et al., 2000 [PubMed 10753632]).[supplied by OMIM, Mar 2008]
