Protein existenceEvidence at protein level

General annotation (Comments)

Function

May act as a negative regulator of Ras-mediated mitogenic activity. Plays a role in ciliogenesis By similarity. Ref.1

Catalytic activity

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Subunit structure

Interacts with GRAP2 and GRB2 By similarity.

Subcellular location

Nucleus By similarity. Cytoplasm By similarity. Cytoplasmic vesicle. Endosome By similarity. Cytoplasm › cytoskeleton › cilium basal body By similarity Ref.1.

Tissue specificity

Ubiquitously expressed, with highest levels in brain, testis and kidney, and lowest levels in skeletal muscle. Ref.1 Ref.3

Sequence similarities

Belongs to the protein-tyrosine phosphatase family. Non-receptor class subfamily.

Contains 1 BRO1 domain.

Contains 2 TPR repeats.

Contains 1 tyrosine-protein phosphatase domain.

Sequence caution

The sequence AAC62959.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.

The sequence AAC62959.1 differs from that shown. Reason: Frameshift at positions 1302 and 1364.
