HOXA10

A gene on chromosome 7p15.2 that encodes a sequence-specific transcription factor of a developmental regulatory system, which provides cells with specific positional identities on the anterior-posterior axis and appears to be involved in gene expression, morphogenesis and differentiation. The HOXA10 protein product may play a role in fertility, embryo viability and in regulating the commitment of hematopoietic cell lineage.
