GU repeat RNA binding

Binding to an RNA molecule containing GU repeats.

box C/D methylation guide scaRNP complex

A ribonucleoprotein complex containing a small CB-specific RNA (scaRNA), with a short sequence motif (GU/UG wobble stem) for CB localization that is capable of methylation of target RNAs.

obsolete transcription factor activity, RNA polymerase I enhancer sequence-specific binding

OBSOLETE. Binding to a RNA polymerase I (Pol I) enhancer in order to modulate transcription by RNA polymerase I.

collagen type I trimer

A collagen trimer containing alpha(I) chains. The most common form of type I collagen is a heterotrimer containing two alpha1(I) chains and one alpha2(I) chain; homotrimers containing three alpha1(I) chains are also found. Type I collagen triple helices associate to form banded fibrils.

transcription by RNA polymerase I

The synthesis of RNA from a DNA template by RNA polymerase I (RNAP I), originating at an RNAP I promoter.

type-I cohesin domain binding

Binding to a type-I cohesin domain of a protein. Type-I cohesin domain is the binding partner of type-I dockerin domain.

MHC class I receptor activity

Combining with an MHC class I protein complex to initiate a change in cellular activity. Class I here refers to classical class I molecules.

rhamnogalacturonan endolyase activity

Catalysis of the reaction: H2O + a rhamnogalacturonan type I = [rhamnogalacturonan I oligosaccharide]-alpha-L-rhamnose + 4-deoxy-4,5-unsaturated D-galactopyranosyluronate-[rhamnogalacturonan I oligosaccharide].

peptide antigen assembly with MHC class I protein complex

The binding of a peptide to the antigen binding groove of an MHC class I protein complex. Class I here refers to classical class I molecules.

15-hydroxyprostaglandin-I dehydrogenase (NADP+) activity

Catalysis of the reaction: NADP+ + prostaglandin I(2) = 15-dehydro-prostaglandin I(2) + H+ + NADPH.
