Naturally occurring peptide that is an opioid (any non-alkaloid having an opiate-like effect that can be reversed by naloxone or other recognized morphine antagonist). These include Leu- and Met-enkephalin, dynorphin and neoendorphin, alpha, beta, gamma and delta endorphins formed from beta-lipotropin, various pronase-resistant peptides such as beta casamorphin, and other peptides whose opiate-like action seems to be indirect.

The formation from simpler components of prostaglandins, any of a group of biologically active metabolites which contain a cyclopentane ring.

synaptic vesicle fusion to presynaptic membrane

Fusion of the membrane of a synaptic vesicle with its target presynaptic membrane, thereby releasing its cargo neurotransmitters into the synaptic cleft.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate + N-acetyl-D-glucosamine = adenosine 3',5'-bisphosphate + N-acetyl-D-glucosamine 6-sulfate.

A sodium channel in a cell membrane whose opening is governed by the membrane potential.

The posttranslational conversion of C-terminal glycine-extended peptides to C-terminal alpha-amidated peptides. Occurs to over half of all peptide hormones to give bioactive peptides. This is a two step process catalyzed by a peptidyl-glycine alpha-hydroxylating monooxygenase and a peptidyl-alpha-hydroxyglycine alpha-amidating lyase. In some organisms, this process is catalyzed by two separate enzymes, whereas in higher organisms, one polypeptide catalyzes both reactions.

Determination of the site in the cell at which a prehair initiates outgrowth. Restriction of prehair initiation to the distalmost part of a cell is essential to ensure that each wing epithelial cell produces one adult hair that points distally.

Interacting selectively with beta-amyloid peptide/protein and/or its precursor.

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

Processes leading to rupture the of the follicle releasing the central located oocyte. As in, but not restricted to, mammals (Mammalia, ncbi_taxonomy_id:40674).
