Combining with a molecular pattern based on a repeating or polymeric structure, such as a polysaccharide or peptidoglycan, to initiate a change in cell activity. Such molecular patterns are sometimes associated with potential pathogens.

The process of apoptosis in neutrophils.

The process of regulating the proliferation and elimination of B cells such that the total number of B cells within a whole or part of an organism are stable over time in the absence of an outside stimulus.

Catalysis of the reaction: arachidonate + O2= (5Z,8Z,11Z,13E)-(15S)-15-hydroperoxyicosa-5,8,11,13-tetraenoate.

Interacting selectively with a phosphorylated tyrosine residue within a protein.

Combining with prostaglandin J (PGJ(2)), a metabolite of prostaglandin D (PGD(2)) to initiate a change in cell activity.

Interacting selectively with phosphatidylserine, a class of glycophospholipids in which a phosphatidyl group is esterified to the hydroxyl group of L-serine.

Cytolysis of target cells by natural killer cells, eosinophils, neutrophils, monocytes, or macrophages following engagement of antibodies bound to the target cells by Fc receptors on the effector cells.

Interacting selectively with 7S RNA, the RNA component of the signal recognition particle (SRP).

The outer membrane of a muscle fiber, consisting of the plasma membrane, a covering basement membrane (about 100 nm thick and sometimes common to more than one fiber), and the associated loose network of collagen fibers.

A change in state or activity of an organism(in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of exposure to an organic substance.

The assembly of a cilium, a specialized eukaryotic locomotor organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.

A change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of exposure to an inorganic substance.
