Hox-2.3, MOUSE, HOMOLOG OF


HGNC Approved Gene Symbol: HOXB7

Cytogenetic location: 17q21.32   Genomic coordinates (GRCh38) : 17:48,607,232-48,611,017 (from NCBI)


TEXT

Cloning and Expression

Simeone et al. (1987) characterized 2 human cDNA clones, each containing a homeobox region. The corresponding genes, termed c1 (HOXB7) and c8 (HOXC6; 142972), were evaluated in different organs and body parts during human embryonic and fetal development. Differential expression suggested that the genes play a key role in a variety of developmental processes.


Gene Function

In mouse, Hoxb7 expression is confined to macrophages. Using RT-PCR, Lill et al. (1995) detected expression of HOXB7 in monocytes differentiated from HL60 cells by stimulation with vitamin D3. Overexpression of HOXB7 inhibited differentiation into granulocytes but not monocytes. However, RT-PCR analysis failed to detect HOXB7 expression in mature monocytes.


Biochemical Features

HOX proteins have a conserved DNA-binding homeodomain, a pentapeptide motif that mediates interactions with PBX proteins (e.g., PBX1; 176310), and an N-terminal octapeptide motif. Yaron et al. (2001) found that wildtype HOXB7 inhibited differentiation of a murine myelomonocytic cell line, 32D, but that mutations in any of the conserved regions blocked this inhibitory effect. Mutations in casein kinase phosphorylation sites, the glutamate-rich C terminus, or the N-terminal 14 residues of HOXB7 enhanced 32D differentiation.


Mapping

As reviewed by Acampora et al. (1989), the HOXB7 (HOX2C) gene resides in the homeobox region-2 gene cluster on chromosome 17 between the HOXB8 (HOX2D; 142963) and HOXB6 (HOX2B; 142961) genes.
