Summary
Description
Negatively regulates the activity of members of the MAP kinase family in response to changes in the cellular environment. Has a specificity for the ERK family. Acts as negative regulator in a variety of developmental processes including cell differentiation and proliferation controlled by the Ras/ERK pathway. Suppresses the photoreceptor cell differentiation and wing vein formation. Required for proper oogenesis and early embryogenesis. Functions autonomously in a subset of photoreceptor progenitor cells in eye imaginal disks. Appears also to be required in surrounding non-neuronal cells for ommatidial patterning and photoreceptor differentiation. Plays a role in the maintenance of epithelial integrity during tracheal development.
Catalytic Activity
H2O + O-phospho-L-threonyl-[protein] = L-threonyl-[protein] + phosphate
H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] + phosphate
H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] + phosphate
Subunit
Interacts (via N-terminal region) with phosphorylated rl.
Similarity
Belongs to the protein-tyrosine phosphatase family. Non-receptor class dual specificity subfamily.
