Catalysis of the reaction: L-arginine + glycine = L-ornithine + guanidinoacetate.

A sodium channel in a cell membrane whose opening is governed by the membrane potential.

The change in morphology and behavior of a mature or immature T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific.

The change in morphology and behavior of a mature or immature B cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific.

A change in morphology and behavior of a macrophage resulting from exposure to a cytokine, chemokine, cellular ligand, pathogen, or soluble factor.

The change in morphology and behavior of a monocyte resulting from exposure to a cytokine, chemokine, cellular ligand, pathogen, or soluble factor.

Interacting selectively with beta-amyloid peptide/protein and/or its precursor.

The process whose specific outcome is the progression of the ovarian follicle over time, from its formation to the mature structure.

The change in morphology and behavior of a neutrophil resulting from exposure to a cytokine, chemokine, pathogen, or soluble factor.

Any process that contributes to the success of sperm fertilization in multiply-mated females.

Combining with gastrin to initiate a change in cell activity.

Combining with secretin to initiate a change in cell activity.

A multiprotein complex that consists of at least three proteins, CD14, TLR4, and MD-2, each of which is glycosylated.

Combining with the corticotrophin-releasing factor family of ligands, including the urocortins, to initiate a change in cell activity.

The cellular and vascular changes occurring in the endometrium of the pregnant uterus just after the onset of blastocyst implantation. This process involves the proliferation and differentiation of the fibroblast-like endometrial stromal cells into large, polyploid decidual cells that eventually form the maternal component of the placenta.

Combining with thrombin to initiate a change in cell activity.
