The process of binding or confining any triester of glycerol such that it is separated from other components of a biological system.

Catalysis of the reaction: S-adenosyl-L-methionine + guanidinoacetate = S-adenosyl-L-homocysteine + creatine.

Catalysis of the reaction: L-gulono-1,4-lactone + O2 = L-xylo-hex-3-ulonolactone + H2O2.

Addition of multiple ubiquitin moieties to a protein, forming a ubiquitin chain.

Repression of transcription of centromeric DNA by the formation of heterochromatin.

Construction of the eggshell, a product of the somatic follicle cell epithelium and a structure that supports the egg in a hostile environment, minimizing water loss whilst allowing gas exchanges essential for embryonic respiration.

Construction of the vitelline membrane portion of the egg shell, a rigid structure required to maintain the shape of the egg.

The directed movement of substances along cytoskeletal elements such as microfilaments or microtubules within a cell.

oocyte cell differentiation (sensu Insecta)

Processes whereby one relatively unspecialized one immature cystocyte of the germ-line cyst acquires the specialized features of an oocyte. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

ovarian follicle cell development (sensu Insecta)

The process that occurs during oogenesis involving the ovarian follicle cells, somatic cells which surround the germ cells of an ovary. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

female germ-line cyst encapsulation (sensu Insecta)

Formation of a single follicular epithelium around the germ-line derived cells of a cyst formed in the female gonad. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

The splitting off of border cells from the anterior epithelium, prior to border cell migration.

Catalysis of the reaction: acyl-CoA + sphingosine = CoA + N-acylsphingosine. In S. cerevisiae, either dihydrosphingosine (DHS) or phytosphingosine (PHS) can react with C26-fattyacyl-CoA to produce ceramide-I or ceramide-II (also called phytoceramide) respectively. In mammals, DHS is usually acylated with a C18 fatty acid group.
