Catalysis of the reaction: D-ribose 5-phosphate = D-ribulose 5-phosphate.

The process whereby a relatively unspecialized cell acquires specialized features of a striated muscle cell; striated muscle fibers are divided by transverse bands into striations, and cardiac and voluntary muscle are types of striated muscle.

Catalysis of the reaction: ATP + selenide + H2O = AMP + selenophosphate + phosphate.

transmembrane receptor protein tyrosine kinase signaling protein activity

transmembrane receptor protein tyrosine kinase signalling protein activity

regulation of muscle cell differentiation

Any process that modulates the frequency, rate or extent of muscle cell differentiation.

Catalysis of the reaction: 7,8-dihydrobiopterin + NADP+ = sepiapterin + NADPH + H+.

negative regulation of muscle cell differentiation

Any process that stops, prevents or reduces the rate of muscle cell differentiation.

Catalysis of the reaction: palmitoyl-CoA + L-serine = CoA + 3-dehydro-D-sphinganine + CO2.

transmembrane receptor protein tyrosine kinase adaptor protein activity

Catalysis of the reaction: a carboxylic ester + H2O = an alcohol + a carboxylate.

transmembrane receptor protein tyrosine kinase docking protein activity

positive regulation of cell organization and biogenesis

positive regulation of cell organisation and biogenesis

Any process that activates or increases the rate of the processes involved in the assembly and arrangement of cell structures, including the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.

Catalysis of the reaction: ATP + SO4(2-) (sulfate) = diphosphate + adenylylsulfate.

peroxisome targeting signal receptor activity

Combining with a peroxisome targeting signal to initiate a change in cell activity.

The change in morphology and behavior of a mature or immature natural killer T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific.

Catalysis of the reaction: 3-sulfino-L-alanine = hypotaurine + CO2.
