Gene families with members on the human Hox-bearing chromosomes. Note that many of these gene families cluster to restricted regions of the chromosomes. A subset of genes are located on chromosome 3, probably due to a translocation. ACCN, amiloride-sensitive cation channels; ACT, actins; ATP5G, ATPase; CACNBs, calcium channel β subunits; fibr COL, fibrillar associated collagens; DLX, distal-less homeo box; EGFR/ERBB, epidermal growth factor receptor/erythroblastoma; EVX, even-skipped homeo box; FZD, frizzled; GBX, gastrulation brain homeo box; GLI, glioma-associated oncogene homolog belonging to Krüppel family; HH, hedgehog; HOX, homeo box (antennapedia-like); IFs type III, intermediate filaments type III; IGFBP, insulin-like growth factor-binding protein; INHB, inhibins; ITGA, integrin α chains; ITGB, integrin β chains; MEOX, mesenchyme homeo box; MYL, myosin light chains; NFE2, nuclear factor erythroid; NOS, nitric oxide synthase; Nuclear rec's, nuclear hormone receptors; RAB, member of Ras-oncogene family; RAMP, receptor activity-modifying protein; SCNA, sodium channel α subunits; SLC4, solute carrier family 4 (anion exchangers); SMARC, SWI/SNF-related matrix-associated actin-dependent regulator of chromatin; SP, transcription factor Sp; STAT, signal transducers and activators of transcription.
