CC -!- FUNCTION: Transcription factor that is involved in the regulation of
CC cell proliferation, apoptosis and embryonic development (By
CC similarity). Plays an important role in the development of several
CC organs, including kidney, muscle and inner ear (By similarity).
CC Depending on context, functions as transcriptional repressor or
CC activator (By similarity). Lacks an activation domain, and requires
CC interaction with EYA family members for transcription activation
CC (PubMed:15141091). Mediates nuclear translocation of EYA1 and EYA2
CC (PubMed:19497856). Binds the 5'-TCA[AG][AG]TTNC-3' motif present in the
CC MEF3 element in the MYOG promoter and CIDEA enhancer (PubMed:27923061,
CC PubMed:23435380, PubMed:15141091, PubMed:19497856). Regulates the
CC expression of numerous genes, including MYC, CCND1 and EZR (By
CC similarity). Acts as activator of the IGFBP5 promoter, probably
CC coactivated by EYA2 (By similarity). Repression of precursor cell
CC proliferation in myoblasts is switched to activation through
CC recruitment of EYA3 to the SIX1-DACH1 complex (By similarity). During
CC myogenesis, seems to act together with EYA2 and DACH2 (By similarity).
CC Regulates the expression of CCNA1 (PubMed:15123840). Promotes brown
CC adipocyte differentiation (By similarity).

CC entry.
CC -!- DISEASE: Branchiootic syndrome 3 (BOS3) [MIM:608389]: A syndrome
CC characterized by usually bilateral branchial cleft fistulas or cysts,
CC sensorineural and/or conductive hearing loss, pre-auricular pits, and
CC structural defects of the outer, middle or inner ear. Otic defects
CC include malformed and hypoplastic pinnae, a narrowed external ear
CC canal, bulbous internal auditory canal, stapes fixation, malformed and
CC hypoplastic cochlea. Branchial and otic anomalies overlap with those
CC seen in individuals with the branchiootorenal syndrome. However renal
CC anomalies are absent in branchiootic syndrome patients.
CC {ECO:0000269|PubMed:15141091, ECO:0000269|PubMed:17637804,

CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- DISEASE: Note=Defects in SIX1 could be a cause of branchiootorenal
CC syndrome (BOR). BOR is an autosomal dominant disorder manifested by
CC various combinations of preauricular pits, branchial fistulae or cysts,
CC lacrimal duct stenosis, hearing loss, structural defects of the outer,
CC middle, or inner ear, and renal dysplasia. Associated defects include
CC asthenic habitus, long narrow facies, constricted palate, deep
CC overbite, and myopia. Hearing loss may be due to mondini type cochlear
CC defect and stapes fixation. Penetrance of BOR syndrome is high,
CC although expressivity can be extremely variable.
CC {ECO:0000305|PubMed:15141091, ECO:0000305|PubMed:19497856}.
CC -!- SIMILARITY: Belongs to the SIX/Sine oculis homeobox family.
