Storage Instruction
If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual.
This kit recognizes Human APLN in samples. No significant cross-reactivity or interference between Human APLN and analogues was observed.
Sample Type
Serum, plasma and other biological fluids
Additional Info
Post Translational Modifications
Several active peptides may be produced by proteolytic processing of the peptide precursor.
Function
Peptide hormone that functions as endogenous ligand for the G-protein-coupled apelin receptor (APLNR/APJ), that plays a role in cadiovascular homeostasis. Functions as a balanced agonist activating both G(i) protein pathway and beta-arrestin pathway of APLNR. Downstream G proteins activation, apelin can inhibit cAMP production and activate key intracellular effectors such as ERKs. On the other hand, APLNR activation induces beta-arrestin recruitment to the membrane leading to desensitization and internalization of the receptor. Apelin blunts cardiac hypertrophic induction from APLNR on response to pathological stimuli, but also induces myocardial hypertrophy under normal conditions. Apelin-36 dissociates more hardly than (pyroglu)apelin-13 from APLNR. Involved in the regulation of cardiac precursor cell movements during gastrulation and heart morphogenesis. Has an inhibitory effect on cytokine production in response to T-cell receptor/CD3 cross-linking.the oral intake of apelin in the colostrum and the milk might therefore modulate immune responses in neonates. Plays a role in early coronary blood vessels formation. Mediates myocardial contractility in an ERK1/2-dependent manner. May also have a role in the central control of body fluid homeostasis by influencing vasopressin release and drinking behavior. (Microbial infection) Endogenous ligand for the apelin receptor (APLNR), an alternative coreceptor with CD4 for HIV-1 infection. Inhibits HIV-1 entry in cells coexpressing CD4 and APLNR. Apelin-36 has a greater inhibitory activity on HIV infection than other synthetic apelin derivatives.
