oocyte fate determination (sensu Insecta)

oocyte cell fate determination (sensu Insecta)

Process by which a cell becomes capable of differentiating autonomously into an oocyte cell regardless of its environment; upon determination, the cell fate cannot be reversed. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

Growth of the egg chamber between the time it leaves the germarium and the onset of vitellogenesis. During this time both nurse cells and the oocyte undergo developmental changes including nuclear organization and cytoplasmic growth. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

The directed movement of follicle cells that takes place during oogenesis. During egg chamber formation, follicle cells migrate to envelop the germ-line cysts and move in between cysts. At stage 10B, follicle cells migrate centripetally between the nurse cells and the oocyte, enclosing the anterior of the egg. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

border follicle cell migration (sensu Insecta)

The directed movement of the border cells through the nurse cells to reach the oocyte. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

The attachment of a somatic follicle cell to another somatic follicle cell or to its substratum, the germline cells. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

The formation from simpler components of keratan sulfate, a glycosaminoglycan with repeat units consisting of beta-1,4-linked D-galactopyranosyl-beta-(1,4)-N-acetyl-D-glucosamine 6-sulfate and with variable amounts of fucose, sialic acid and mannose units; keratan sulfate chains are covalently linked by a glycosidic attachment through the trisaccharide galactosyl-galactosyl-xylose to peptidyl-threonine or serine residues.

The formation of a covalent cross-link between or within protein chains.

Catalysis of the reaction: N6,N6,N6-trimethyl-L-lysine + 2-oxoglutarate + O2 = 3-hydroxy-N6,N6,N6-trimethyl-L-lysine + succinate + CO2.
