The chemical reactions involving dermatan sulfate proteoglycan, any glycoprotein whose glycosaminoglycan units are dermatan sulfate (chondroitin sulfate B). Dermatan sulfate is a glycosaminoglycan with repeats consisting of beta-(1,4)-linked L-iduronyl-beta-(1,3)-N-acetyl-D-galactosamine 4-sulfate units.

positive regulation of interleukin-13 biosynthesis

positive regulation of interleukin-13 synthesis

Any process that activates or increases the rate, frequency or extent of the formation from simpler components of interleukin-13.

Interacting selectively with 3'-phosphoadenosine 5'-phosphosulfate (PAPS), a naturally occurring mixed anhydride. It is an intermediate in the formation of a variety of sulfo compounds in biological systems.

The directed movement of nucleic acids, single or double-stranded polynucleotides involved in the storage, transmission and transfer of genetic information, into, out of, within or between cells.

The directed movement of RNA, ribonucleic acids, into, out of, within or between cells.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate + N-acetyl-D-galactosamine 4-sulfate (in chondroitin sulfate) = adenosine 3',5'-bisphosphate + N-acetyl-D-galactosamine 4,6-bissulfate. Functions on nonreducing terminal and internal GalNAc(4SO(4)) residues contained in chondroitin sulfate A and dermatan sulfate (chondroitin sulfate B).

Catalysis of the reaction: (S)-lactate + 2 ferricytochrome c = pyruvate + 2 ferrocytochrome c.

The formation from simpler components of interferon-beta.

Catalysis of the reaction: UDP-galactose + D-glucose = UDP + lactose.

The formation from simpler components of interferon type I.

Catalysis of the reaction: (R)-S-lactoylglutathione = glutathione + methylglyoxal.

negative regulation of epithelial cell proliferation

Any process that stops, prevents or reduces the rate or extent of epithelial cell proliferation.

Catalysis of the reaction: (7E,9E,11Z,14Z)-(5S,6S)-5,6-epoxyicosa-7,9,11,14-tetraenoate + H2O = (6Z,8E,10E,14Z)-(5S,12R)-5,12-dihydroxyicosa-6,8,10,14-tetraenoate.
