General annotation (Comments)

Function

Probable pseudophosphatase. Lacks several amino acids in the catalytic pocket which renders it catalytically inactive as a phosphatase. The pocket is however sufficiently preserved to bind phosphorylated substrates, and maybe protect them from phosphatases. Inhibits myoblast differentiation in vitro and induces oncogenic transformation in fibroblasts. According to Ref.9, may function as a guanine nucleotide exchange factor (GEF) activating RAB28. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form. Ref.4 Ref.9

Subunit structure

Interacts with the SET domain of MLL/HRX. Interacts with SUV39H1. Ref.4 Ref.6

Subcellular location

Nucleus Ref.4.

Sequence similarities

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

Contains 1 dDENN domain.

Contains 1 DENN domain.

Contains 1 GRAM domain.

Contains 1 myotubularin phosphatase domain.

Contains 1 PH domain.

Contains 1 uDENN domain.

Sequence caution

The sequence AAC39675.1 differs from that shown. Reason: Frameshift at positions 1603, 1627, 1631 and 1864.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: O95248-1)
