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.

Increase in size of antral follicles due to cell proliferation and/or growth of the antral cavity.

The chemical reactions involving any proteoglycan containing heparan sulfate, any member of a group of glycosaminoglycans that have repeat units consisting of alternating alpha1-

proton-transporting ATP synthase complex, catalytic core F(1)

hydrogen-transporting ATP synthase, F1 sector

The sector of a hydrogen-transporting ATP synthase complex in which the catalytic activity resides; it comprises the catalytic core and central stalk, and is peripherally associated with a membrane, such as the plasma membrane or the mitochondrial inner membrane, when the entire ATP synthase is assembled.

The chemical reactions involving heparin, any member of a group of glycosaminoglycans found mainly as an intracellular component of mast cells. They are similar to heparan sulfates but are of somewhat higher average Mr (6000-20000) and contain fewer N-acetyl groups and more N-sulfate and O-sulfate groups; they may be attached in the same manner to protein, forming proteoglycans. They consist predominantly of alternating alpha1-

The chemical reactions involving glycosaminoglycans, any one of a group of polysaccharides that contain amino sugars. Formerly known as mucopolysaccharides, they include hyaluronic acid and chondroitin, which provide lubrication in joints and form part of the matrix of cartilage. The three-dimensional structure of these molecules enables them to trap water, which forms a gel and gives glycosaminoglycans their elastic properties.
