Comments

FUNCTION: Tyrosine phosphatase that specifically dephosphorylates 'Tyr-142' of histone H2AX (H2AXY142ph). 'Tyr-142' phosphorylation of histone H2AX plays a central role in DNA repair and acts as a mark that distinguishes between apoptotic and repair responses to genotoxic stress. Promotes efficient DNA repair by dephosphorylating H2AX, promoting the recruitment of DNA repair complexes containing MDC1. Its function as histone phosphatase probably explains its role in transcription regulation during organogenesis. Seems to coactivate SIX2, SIX4 and SIX5. May be required for normal development of branchial arches, ear and kidney.
CATALYTIC ACTIVITY: Protein tyrosine phosphate + H₂O = protein tyrosine + phosphate.
COFACTOR: Binds 1 Mg(2+) ion per subunit (By similarity).
SUBUNIT: Probably interacts with SIX2, SIX4 and SIX5 (By similarity).
SUBCELLULAR LOCATION: Cytoplasm (By similarity). Nucleus. Note=Localizes at sites of DNA damage at double-strand breaks (DSBs).
ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing.

Name EYA1A

Isoform ID Q99502-1

This is the isoform sequence displayed in this entry.

Name EYA1B

Isoform ID Q99502-2

Features which should be applied to build the isoform sequence: VSP_001486.
TISSUE SPECIFICITY: In the embryo, highly expressed in kidney with lower levels in brain. Weakly expressed in lung. In the adult, highly expressed in heart and skeletal muscle. Weakly expressed in brain and liver. No expression in eye or kidney.
DEVELOPMENTAL STAGE: Detected in cytoplasm of somite cells at the beginning of fourth week of development. Detected in cytoplasm of limb bud cell between the sixth and eighth week of development.
DISEASE: Defects in EYA1 are the cause of branchiootorenal syndrome type 1 (BOR1) [MIM:113650]; also known as Melnick-Fraser syndrome. BOR is an autosomal dominant disorder manifested by various combinations of preauricular pits, branchial fistulae or cysts, lacrimal duct stenosis, hearing loss, structural defects of the outer, middle, or inner ear, and renal dysplasia. Associated defects include asthenic habitus, long narrow facies, constricted palate, deep overbite, and myopia. Hearing loss may be due to mondini type cochlear defect and stapes fixation. Penetrance of BOR syndrome is high, although expressivity can be extremely variable.
DISEASE: Defects in EYA1 are the cause of otofaciocervical syndrome [MIM:166780]. The syndrome is characterized by trophic alterations of the facies and shoulder girdle in addition to the malformations seen in BOR.
DISEASE: Defects in EYA1 are the cause of branchiootic syndrome type 1 (BOS1) [MIM:602588]; also known as BO syndrome type 1 or branchiootic dysplasia. Individuals with BOS1 are affected by the same branchial and otic anomalies as those seen in individuals with BOR1, but lack renal anomalies.
SIMILARITY: Belongs to the HAD-like hydrolase superfamily. EYA family.
