General annotation (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. May be involved in development of the eye By similarity. |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. |
| Cofactor | Binds 1 Mg2+ ion per subunit By similarity. |
| Subcellular location | |
| Tissue specificity | Highly expressed in heart and skeletal muscle. Ref.6 |
| Involvement in disease | Deafness, autosomal dominant, 10 (DFNA10) [MIM:601316]: A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. Cardiomyopathy, dilated 1J (CMD1J) [MIM:605362]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. Cardiomyopathy dilated type 1J is characterized by the association of sensorineural hearing loss and dilated cardiomyopathy in the absence of other anomalies. |
| Sequence similarities | Belongs to the HAD-like hydrolase superfamily. EYA family. |
Ontologies
Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: O95677-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: O95677-2) The sequence of this isoform differs from the canonical sequence as follows: 70-92: Missing. 93-93: M → V | ||||||
| Isoform 3 (identifier: O95677-3) The sequence of this isoform differs from the canonical sequence as follows: 447-452: STYSFA → RCKRRG 453-639: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 4 (identifier: O95677-4) The sequence of this isoform differs from the canonical sequence as follows: 589-613: MQRFGRKVVYVVIGDGVEEEQAAKK → VSRFGTNITYVVIGDGRDEEHAANQ | ||||||
| Isoform 5 (identifier: O95677-5) The sequence of this isoform differs from the canonical sequence as follows: 70-123: Missing. 589-613: MQRFGRKVVYVVIGDGVEEEQAAKK → VSRFGTNITYVVIGDGRDEEHAANQ |
