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

negative regulation of keratinocyte differentiation

Any process that stops, prevents or reduces the rate, frequency or extent of keratinocyte differentiation.

Catalysis of the reaction: ATP + pyridoxal = ADP + pyridoxal 5'-phosphate.

positive regulation of keratinocyte differentiation

Any process that activates or increases the rate, frequency or extent of keratinocyte differentiation.

Catalysis of the reaction: tRNA guanine + queuine = tRNA queuine + guanine.

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

Catalysis of the hydrolysis of terminal, non-reducing beta-D-glucose residues with release of beta-D-glucose.

Catalysis of the inactivation of bleomycin B2 (a cytotoxic glycometallopeptide) by hydrolysis of a peptide bond of beta-aminoalanine, but also shows general aminopeptidase activity. The specificity varies somewhat with source, but amino acid arylamides of Met, Leu and Ala are preferred.

Catalysis of the reaction: GDP-L-fucose + N4-{N-acetyl-beta-D-glucosaminyl-(1,2)-alpha-D-mannosyl-(1,3)-[N-acetyl-beta-D-glucosaminyl-(1,2)-alpha-D-mannosyl-(1,6)]-beta-D-mannosyl-(1,4)-N-acetyl-beta-D-glucosaminyl-(1,4)-N-acetyl-beta-D-glucosaminyl}asparagine = GDP + N4-{N-acetyl-beta-D-glucosaminyl-(1,2)-alpha-D-mannosyl-(1,3)-[N-acetyl-beta-D-glucosaminyl-(1,2)-alpha-D-mannosyl-(1,6)]-beta-D-mannosyl-(1,4)-N-acetyl-beta-D-glucosaminyl-(1,4)-[alpha-L-fucosyl-(1,6)]-N-acetyl-beta-D-glucosaminyl}asparagine.

Catalysis of the reaction: 2-polyprenyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-methionine = 2-polyprenyl-3-methyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-homocysteine.

Stops, prevents or reduces the activity of protein kinase C, an enzyme which phosphorylates a protein.

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

calcium-dependent protein kinase inhibitor activity
