RhCG and H+ATPases are located within the same cellular protein complex in the kidney and this interaction is required for maximal urinary acidification by H+-ATPases, a prerequisite for efficient NH3 secretion and urine excretion of NH4+.
Title: The ammonia transporter RhCG modulates urinary acidification by interacting with the vacuolar proton-ATPases in renal intercalated cells.
RHCG was down-regulated in cervical cancers compared to that in normal cervical tissues, and further decreased in cervical cancer cell lines. Functionally, RHCG overexpression reduced cervical cancer cell proliferation and migration, as evidenced by the decreased transforming growth factor (TGF)-beta1, matrix metalloproteinase (MMP)-2 and MMP-9 expressions in cancer cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: VALIDATED

Description

Transcript Variant: This variant (2) differs in the use of an alternate 3' splice site, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
