General annotation (Comments)

Function

May function in signaling pathways during bone remodeling, as well as serve a broader role in cell interactions associated with differentiation in bone and testis. Associated with differentiation in bone and testis.

Catalytic activity

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Subcellular location

Membrane; Single-pass type I membrane protein.

Tissue specificity

Bone and testis. In the latter, restricted to the basal portion of the seminiferous tubule.

Developmental stage

Up-regulated in differentiating cultures of primary osteoblasts and down-regulated in late stage mineralizing cultures. In testis, expression is highest between stages I and VII when maturing spermatids remain buried within the Sertoli epithelium.

Induction

By parathyroid hormone and cAMP analogs.

Post-translational modification

The cytoplasmic domain contains potential phosphorylation sites.

Sequence similarities

Belongs to the protein-tyrosine phosphatase family. Receptor class 3 subfamily.

Contains 10 fibronectin type-III domains.

Contains 2 tyrosine-protein phosphatase domains.

Biophysicochemical properties

pH dependence:

Optimum pH is 5.6.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Select]

Note: A presumed alternate transcript of 4.8-5.0 kilobases, which may lack PTP domains, is present in proliferating osteoblasts, but not detectable at other stages.
Isoform 1 (identifier: Q64612-1)

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: Q64612-2)

The sequence of this isoform is not available.
Note: No experimental confirmation available.
