Function

Functions both as protein phosphatase and as transcriptional coactivator for SIX1, and probably also for SIX2, SIX4 and SIX5. Tyrosine phosphatase that dephosphorylates 'Tyr- 142' of histone H2AX (H2AXY142ph) and promotes efficient DNA repair via the recruitment of DNA repair complexes containing MDC1. '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. Its function as histone phosphatase may contribute to its function in transcription regulation during organogenesis (By similarity). Plays an important role in hypaxial muscle development together with SIX1 and DACH2; in this it is functionally redundant with EYA1. {ECO:0000250, ECO:0000269PubMed:10490620, ECO:0000269PubMed:17098221}.

Subcellular Localization

Cytoplasm {ECO:0000269PubMed:10490620}. Nucleus {ECO:0000269PubMed:10490620}. Note=Retained in the cytoplasm via interaction with GNAZ and GNAI2 (By similarity). Interaction with SIX1, SIX2, SIX4 or SIX5 is required for translocation to the nucleus. {ECO:0000250}.

Disease Associations

Tissue Specificity

Extensively expressed in cranial placodes, branchial arches, CNS and developing eye and nose. Low expression in lung with little or no expression in skin, liver, intestine and kidney. Predominantly expressed in the upper one-third of the oxyntic mucosa and in most regions of the pyloric mucosa. {ECO:0000269PubMed:16476741}.
