Protein attributes

Sequence length	188 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Catalytic activity	Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. A phosphoprotein + H2O = a protein + phosphate.
Subcellular location	Cytoplasm By similarity.
Tissue specificity	Skeletal muscle-specific. Ref.1
Developmental stage	Expressed at very low levels in myotubes and early postnatal muscle. Expression markedly increases at approximately the 3rd week after birth and continues to increase gradually into adulthood. Ref.1
Sequence similarities	Belongs to the protein-tyrosine phosphatase family. Non-receptor class dual specificity subfamily. Contains 1 tyrosine-protein phosphatase domain.

Alternative products

This entry describes 2 isoforms produced by alternative promoter usage. [Align] [Select]

Isoform 1 (identifier: Q6B8I0-1)

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: Q9QYJ7-1)

The sequence of this isoform can be found in the external entry Q9QYJ7-1.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.

Note: Produced by alternative promoter usage. Produced by use of an alternative open reading frames (ORFs).
