Overview of V-ATPase subunits and their respective RefSeq accession numbers.

A list of the current HUGO Gene Nomenclature Committee (HGNC) designations for the known V-ATPase subunits is provided, along with the corresponding subunits described in this report. An augmented naming system (Proposed) is implemented to incorporate the multiple splice variants identified in this analysis.
Notes for Table 1.
Ref - Original cloning paper.
Sp - Species gene was originally cloned from:
B - Bovine; M - Mouse; R - Rat; H - Human; C- Chicken.
K - known variant noted in Smith AN et al (2003).
E - entrez gene entry exists.
L - identified in literature search.
D - cloned in a high-throughput experiment, needs further experimental validation.
#No human transcript could be identified in RefSeq, so the rat ortholog is provided.
*If a novel homolog is discovered for a subunit with no known homologs then the current homolog will be denoted −1 and the novel homolog denoted −2. For example ATP6V1F will become ATP6V1F1 and the novel homolog ATP6V1F2. If additional splice variants of these new homologs are then discovered, the terminology will become, for example, ATP6V1F1v1 and ATP6V1F1v2 etc.
