The process in which a rhodopsin-mediated signaling pathway is adjusted to modulate the sensitivity and response of a visual system to light stimuli (that might vary over more than 6 magnitudes in intensity) without response saturation.

The chemical reactions and pathways resulting in the breakdown of tRNA, transfer RNA, a class of relatively small RNA molecules responsible for mediating the insertion of amino acids into the sequence of nascent polypeptide chains during protein synthesis.

OBSOLETE. Fusion of the synaptic vesicle with the postsynaptic membrane.

A process that converts synaptic vesicles to a state of competence for calcium triggered fusion with the active zone membrane by bringing the two membranes into very close proximity. Priming typically (but not always) occurs after docking (Jahn and Fasshauer, 2012). Primed vesicles are also capable of spontaneously fusing with the active zone membrane.

The initial (indirect) attachment of a synaptic vesicle membrane to the presynaptic active zone membrane, mediated by proteins protruding from the membrane and proteins of the presynaptic active zone cytoplasmic component. Synaptic vesicle tethering is the first step in this process.

The process in which synaptic vesicles are directed to specific destination membranes, mediated by molecules at the vesicle membrane and target membrane surfaces.

Binding to a beta-3 adrenergic receptor.

Binding to a beta-2 adrenergic receptor.

OBSOLETE. A polypeptide hormone that stimulates glucose uptake by muscle and adipose tissue, and promotes glycogenesis, lipogenesis and the synthesis of proteins and nucleic acids.

The action characteristic of ecdysiostatic hormone, a peptide hormone that inhibits ecdysone secretion.

OBSOLETE. Peptide hormones produced by the corpora allata of insects that reversibly inhibit the production of juvenile hormone.
