The solution structure of the homeobox domain of human Homeobox protein DLX-5

Disease

[DLX5_HUMAN] Defects in DLX5 are the cause of split-hand/foot malformation type 1, with sensorineural hearing loss (SHFM1D) [MIM:220600]. A disease characterized by the association of split-hand/foot malformation with deafness. Split-hand/foot malformation is a limb malformation involving the central rays of the autopod and presenting with syndactyly, median clefts of the hands and feet, and aplasia and/or hypoplasia of the phalanges, metacarpals, and metatarsals. Some patients have been found to have mental retardation, ectodermal and craniofacial findings, and orofacial clefting.[1]

Function

[DLX5_HUMAN] Transcriptional factor involved in bone development. Acts as an immediate early BMP-responsive transcriptional activator essential for osteoblast differentiation. Stimulates ALPL promoter activity in a RUNX2-independent manner during osteoblast differentiation. Stimulates SP7 promoter activity during osteoblast differentiation. Promotes cell proliferation by up-regulating MYC promoter activity. Involved as a positive regulator of both chondrogenesis and chondrocyte hypertrophy in the endochondral skeleton. Binds to the homeodomain-response element of the ALPL and SP7 promoter. Binds to the MYC promoter. Requires the 5'-TAATTA-3' consensus sequence for DNA-binding.[2]

About this Structure

2djn is a 1 chain structure with sequence from Homo sapiens. Full experimental information is available from OCA.
