OBSOLETE. Particulate complex of heterogeneous nuclear RNA (hnRNA; a heterogeneous mixture of RNA molecules of high Mr with a rapid turnover rate that occurs in cell nuclei during protein synthesis; it is the form of RNA synthesized in eukaryotes by RNA polymerase II, that which is translated into protein) with protein, which is cell-specific and heterogeneous. The protein component may play a role in the processing of the hnRNA to mRNA.

OBSOLETE. A complex composed of RNA of the small cytoplasmic RNA (scRNA) class and protein, found in the cytoplasm.

A highly soluble, elongated protein complex found in blood plasma and involved in clot formation. It is converted into fibrin monomer by the action of thrombin. In the mouse, fibrinogen is a hexamer, 46 nm long and 9 nm maximal diameter, containing two sets of nonidentical chains (alpha, beta, and gamma) linked together by disulfide bonds.

A protein complex produced by sequentially activated components of the complement cascade inserted into a target cell membrane and forming a pore leading to cell lysis via ion and water flow.

The codon binding activity of a tRNA that positions an activated amino acid, mediating its insertion at the correct point in the sequence of a nascent polypeptide chain during protein synthesis.

OBSOLETE. Feeding behavior in a fully developed and mature organism, as described in insects.

Feeding behavior in a larval (immature) organism.

The process, occurring in the embryo, by which the anatomical structures of the genitalia are generated and organized.

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

The progression of the reproductive system over time from its formation to the mature structure. The reproductive system consists of the organs that function in reproduction.

A collagen homotrimer of alpha1(XV) chains; a chondroitin sulfate proteoglycan often found in specialized basement membranes where it bridges between fibrils.

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.

A collagen homotrimer of alpha1(II) chains; type II collagen triple helices associate to form fibrils.

A collagen homotrimer of alpha1(III) chains; type III collagen triple helices associate to form fibrils.

The series of molecular signals initiated by estrogen binding to an intracellular receptor, and ending with the regulation of a downstream cellular process, e.g. transcription.

A collagen heterotrimer containing type IV alpha chains; [alpha1(IV)]2alpha2(IV) trimers are commonly observed, although more type IV alpha chains exist and may be present in type IV trimers; type IV collagen triple helices associate to form 3 dimensional nets within basement membranes.
