In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development. This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and differentiation. The encoded protein may be involved in the placement of hindbrain segments in the proper location along the anterior-posterior axis during development. Two transcript variants encoding two different isoforms have been found for this gene, with only one of the isoforms containing the homeodomain region. [provided by RefSeq, Jul 2008]
Forensic Context
A study in mice demonstrated that the HOXA1 is a long noncoding RNA located in the 3' end of the HoxA cluster, where it partners with PURB to exert transcriptional silencing of HOXA1 in a switch-like manner at the single-cell level [Flynn and Chang DOI:10.1016/j.stem.2014.05.014].
