Catalysis of the reaction: protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

non-membrane spanning protein tyrosine phosphatase activity

Catalysis of the reaction: a lipid hydroperoxide + 2 reduced glutathione = 2 H2O + lipid + 2 oxidized glutathione.

receptor signaling protein serine/threonine kinase signaling protein activity

receptor signalling protein serine/threonine kinase signalling protein activity

prenylated protein tyrosine phosphatase activity

Functions as a scaffold for the assembly of a multiprotein mitogen-activated protein kinase (MAPK) complex. MAPK scaffold proteins have binding sites for MAPK pathway kinases as well as for upstream signaling proteins.

oxidoreductase activity, acting on diphenols and related substances as donors, cytochrome as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which a diphenol, or related compound, acts as a hydrogen or electron donor and reduces a cytochrome.

Catalysis of the reaction: protoporphyrinogen-IX + O2 = protoporphyrin-IX + H2O2.

oxidoreductase activity, acting on peroxide as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which the peroxide group acts as a hydrogen or electron acceptor.

RNA splicing, via endonucleolytic cleavage and ligation

Splicing of RNA via recognition of the folded RNA structure that brings the 5' and 3' splice sites into proximity and cleavage of the RNA at both the 3' and 5' splice sites by an endonucleolytic mechanism, followed by ligation of the exons.

The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.

Combining with stem cell factor, a cytokine that stimulates mast cell growth and differentiation, to initiate a change in cell activity.

The joining together of exons from one or more primary transcripts of nuclear messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced.
