Summary: Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Acts upstream of or within several processes, including cellular response to ethanol; cellular response to retinoic acid; and nervous system development. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including brain; embryo ectoderm; embryo mesenchyme; genitourinary system; and gut. Used to study Athabaskan brainstem dysgenesis syndrome. Human ortholog(s) of this gene implicated in Athabaskan brainstem dysgenesis syndrome and autistic disorder. Orthologous to human HOXA1 (homeobox A1). [provided by Alliance of Genome Resources, Dec 2024]

A distal enhancer interacting with the Hoxa1 locus through a long-range chromatin loop. Enhancer deletion significantly inhibited expression of RA-induced Hoxa1 and endoderm master control genes. Hoxa1 directly regulates downstream target genes expression and then orchestrates RA-induced early differentiation of ESCs.
Title: A distal enhancer maintaining Hoxa1 expression orchestrates retinoic acid-induced early ESCs differentiation.
we provide evidence that HOXA1 displays an unexpectedly long half-life and demonstrate that PRDM14 can reduce the stability and affect the transcriptional activity of HOXA1.
Title: PRDM14, a putative histone methyl-transferase, interacts with and decreases the stability and activity of the HOXA1 transcription factor.
Proteomic analyses show that HOXA1 physically interacts on chromatin with PBX, MEIS, and PREP family members, but not with TGIF, suggesting that TGIF may have an independent input into HOXA1-bound regions.This study provides new insight into a regulatory network involving combinatorial interactions between HOXA1 and TALE proteins
Title: HOXA1 and TALE proteins display cross-regulatory interactions and form a combinatorial binding code on HOXA1 targets.

Authors found evidence for a high degree of evolutionary conservation of many binding regions and downstream targets of Hoxa1 between mouse and zebrafish.

Data indicate that homeobox A1 (HOXA1) was a direct microRNA miR-30b target in esophageal cancer (EC) cells.

In presence of these inducing agents, lipid accumulation as well as expression of HoxA1, HoxA5, HoxC4 &HoxC8 markedly enhanced. Irrespective of presence or absence of T3, insulin down regulates HoxA10. T3 results in over expression of HoxA5, HoxC4 and HoxC8 genes, whereas insulin up regulates expression of only HoxC8
Title: Fat accumulation in differentiated brown adipocytes is linked with expression of Hox genes.

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.
