Summaries
Gene Group Membership
CYTOSOLIC PROTEIN TYROSINE PHOSPHATASES -
Cytosolic Protein Tyrosine Phosphatases are non-receptor tyrosine phosphatases. The Protein Tyrosine Phosphatases are defined by the active-site signature motif Cys-X5-Arg. (Adapted from FBrf0129980 and PMID:17057753).
Negative Regulators of Epidermal Growth Factor Receptor Signaling Pathway -
Negative regulators of Epidermal Growth Factor Receptor signaling down-regulate the pathway, suppressing the activation of ERK kinase (rl) or acting on downstream effectors.

      Other Comments
      FlyBase curator comment: although GenBank/EMBL/DDBJ: AF323978 refers to Ptpmeg as "split central complex", the ability of a scc allele to complement Ptpmeg phenotypes and to produce full-length Ptpmeg protein suggests that these genes are separate.
      The Ptpmeg product is required for the proper establishment of axon projections in the ellipsoid body and is required for stabilization of already-formed projection patterns in the mushroom body. The phosphatase activity of the protein is needed for these functions.
