NCIt definition : Homeobox protein Hox-A9 (272 aa, 30 kDa) is encoded by the human HOXA9 gene. This
protein is involved in transcriptional regulation that drives embryonic development.;
NCIt note : Homeobox Protein A9 isoforms are class I sequence-specific DNA-binding homeobox transcription
factors potentially involved in morphogenesis and myeloid differentiation; expression
is spatially and temporally regulated during embryonic development. Frameshifted isoform
B contains a distinct C-terminus lacking the homeodomain. HOXA9 acts within a developmental
regulatory system that provides specific anterior-posterior positional identity to
cells. Associated with acute myeloid leukemogenesis, a chimerically fused in-frame
nucleoporin NUP98 amino terminal half to HOXA9 may inhibit differentiation or disrupt
nucleocytoplasmic transport. (from LocusLink, Swiss-Prot, OMIM);
