Protein
Homeobox protein Hox-A1
Gene
Hoxa1, Era-1, Hox-1.6, Hoxa-1
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Acts on the anterior body structures. Seems to act in the maintenance and/or generation of hindbrain segments.
The homeobox domain presumably directs sequence-specific DNA binding. The N-terminal portion of ERA-1-993 may be involved in interactions with one or more other regulatory proteins. Such an interaction could regulate either the DNA-binding activity or the transcriptional regulatory activity of ERA-1-993.
The homeoboxless ERA-1-399 protein could act as a competitive inhibitor of the ERA-1-993 protein by competing for interaction with regulatory protein(s) while being unable to bind to DNA.

Expressioni

Developmental stagei

Expressed along the entire length of the primitive streak. In early neurogenesis it is expressed in lateral and paraxial mesoderm, endoderm and superficial ectoderm or in the neural tube. From late neurogenesis to mid-embryogenesis, it presents similar spatial domains in the lateral mesoderm, endoderm and superficial ectoderm but is not detectable in any part of the hindbrain. At day 8-8.5 post-coitum found in the embryonic mesoderm, anterior to the first somite, up to the cephalic region at the level of the foregut and developing heart. At day 9 post-coitum found in an anterior part of the developing foregut and is restricted to an epithelial cell type. Expression in the gut is found at the level of the second to third branchial bars.1 Publication

Inductioni

By retinoic acid.
