Protein Structure

UniProt Annotation

Function

NOH-1S is a voltage-gated proton channel that mediates the H(+) currents of resting phagocytes and other tissues. It participates in the regulation of cellular pH and is blocked by zinc. NOH-1L is a pyridine nucleotide-dependent oxidoreductase that generates superoxide and might conduct H(+) ions as part of its electron transport mechanism, whereas NOH-1S does not contain an electron transport chain.

Subcellular Localization

Cell projection, invadopodium membrane {ECO:0000269PubMed:19755710}; Multi-pass membrane protein {ECO:0000269PubMed:19755710}.

Disease Associations

Tissue Specificity

NOH-1L is detected in colon, uterus, prostate, and colon carcinoma, but not in peripheral blood leukocytes. NOH- 1S is detected only in colon and colon carcinoma cells.
