Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate + heparin-glucosamine = adenosine 3',5'-bisphosphate + heparin-glucosamine 3-O-sulfate.

positive regulation of glial cell differentiation

positive regulation of neuroglia differentiation

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

Catalysis of the reaction: S-adenosyl-L-methionine + histone-arginine = S-adenosyl-L-homocysteine + histone-N-methyl-arginine.

Catalysis of the hydrolysis of O-sialoglycoproteins; cleaves the -Arg31-Asp32- bond in glycophorin A. Does not cleave unglycosylated proteins, desialylated glycoproteins or glycoproteins that are only N-glycosylated.

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

Catalysis of the release of any N-terminal amino acid, including proline, that is linked with proline, even from a dipeptide or tripeptide.

negative regulation of osteoclast differentiation

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

positive regulation of osteoclast differentiation

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

Catalysis of the reaction: L-alanine + glyoxylate = pyruvate + glycine.

regulation of photoreceptor differentiation (sensu Endopterygota)

Any process that modulates the frequency, rate or extent of photoreceptor differentiation. As in, but not restricted to, the Holometabola (Endopterygota, ncbi_taxonomy_id:33392).

Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + (N-acetyl-beta-D-glucosaminyl-1,2)-alpha-D-mannosyl-1,3-(beta-N-acetyl-D-glucosaminyl-1,2-alpha-D-mannosyl-1,6)-beta-D-mannosyl-R = UDP + N-acetyl-beta-D-glucosaminyl-1,4-(N-acetyl-D-glucosaminyl-1,2)-alpha-D-mannosyl-1,3-(beta-N-acetyl-D-glucosaminyl-1,2-alpha-D-mannosyl-1,6)-beta-D-mannosyl-R.

negative regulation of photoreceptor differentiation (sensu Endopterygota)

Any process that stops, prevents or reduces the rate, frequency or extent of photoreceptor differentiation. As in, but not restricted to, the Holometabola (Endopterygota, ncbi_taxonomy_id:33392).
