paired box protein PAX3 (PAX3, HUP2)

Function: - probable transcription factor - can bind to DNA as a heterodimer with PAX7 - interacts with DAXX Structure: - belongs to the paired homeobox family - contains 1 homeobox DNA-binding domain - contains 1 paired domain Compartment: nucleus Alternative splicing: named isoforms=3 Pathology: - defects in PAX3 are the cause of a) Waardenburg syndrome 1 b) Waardenburg syndrome 3 c) craniofacial-deafness-hand syndrome - chromosomal translocation t(2;13)(q35;q14) involving PAX3 with FOXO1 is a cause of rhabdomyosarcoma 2 - chromosomal translocation t(2;2)(q35;p23) involving PAX3 with NCOA1 is a cause of rhabdomyosarcoma; translocation generates the NCOA1-PAX3 oncogene consisting of the N-terminus part of PAX3 & the C-terminus part of NCOA1; the fusion protein acts as a transcriptional activator
