The function of Ensembl gene identifier ENSG00000167895 (TMC8, transmembrane channel like 8) is as follows. Acts as a regulatory protein involved in the regulation of numerous cellular processes (PubMed:18158319, PubMed:23429285, PubMed:30068544, PubMed:32917726). Together with its homolog TMC6/EVER1, forms a complex with calcium-binding protein CIB1 in lymphocytes and keratynocytes where TMC6 and TMC8 stabilize CIB1 levels and reciprocally (PubMed:30068544, PubMed:32917726). Together with TMC6, also forms a complex with and activates zinc transporter ZNT1 at the ER membrane of keratynocytes, thereby facilitating zinc uptake into the ER (PubMed:18158319). Also inhibits receptor-mediated calcium release from ER stores and calcium activated and volume regulated chloride channels (PubMed:25220380). Down-regulates the activity of transcription factors induced by zinc and cytokines (PubMed:18158319). Also sequesters TRADD which impairs the recruitment of TRAF2 and RIPK1 in the pro-survival complex I and promotes proapoptotic complex II formation, and may therefore be involved in TNF-induced cell death/survival decisions (PubMed:23429285). {ECO:0000269|PubMed:18158319, ECO:0000269|PubMed:23429285, ECO:0000269|PubMed:25220380, ECO:0000269|PubMed:30068544, ECO:0000269|PubMed:32917726}.
