TMC8 — Transmembrane channel like 8
TMC8 belongs to a gene co-expression module in 4 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function
Acts as a regulatory protein involved in the regulation of numerous cellular processes. 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. 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. Also inhibits receptor-mediated calcium release from ER stores and calcium activated and volume regulated chloride channels. Down-regulates the activity of transcription factors induced by zinc and cytokines. 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.
