peroxisome matrix targeting signal-2 binding

Binding to a type 2 peroxisome targeting signal, a nonapeptide with a broad consensus sequence of (R/K)-(L/V/I)-(XXXXX)-(H/Q)-(L/A/F).

gamma-glutamyl carboxylase activity

Catalysis of the reaction: peptidyl-glutamate + reduced vitamin K + CO2 + O2 = peptidyl-gamma-carboxyglutamate + vitamin K epoxide.

substance K receptor binding

Binding to a substance K receptor.

neuromedin K receptor binding

Binding to a neuromedin K receptor.

potassium ion binding

Binding to a potassium ion (K+).

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.
