Phosphatidylethanolamine-binding protein 1(PEBP1).

This basic part encodes Human serine protease inhibitor phosphotidylethanolamine-binding protein 1 which is able to inhibit HtrA1 (BBa_K4165004).


Usage and Biology

ATP, opioids, and phosphatidylethanolamine are all bound. Phosphatidylinositol and phosphatidylcholine have a lesser affinity for it. Inhibits thrombin, neuropsin, and chymotrypsin but not trypsin, tissue type plasminogen activator, and elastase (By similarity). RAF1 kinase activity is inhibited by preventing its activation, dissociating the RAF1/MEK complex, and serving as a competitive inhibitor of MEK phosphorylation. HCNP may be implicated in the function of central nervous system presynaptic cholinergic neurons. HCNP enhances choline acetyltransferase synthesis but not acetylcholinesterase.This type of inhibitor is very effective and has high affinity for trypsin-like proteases (serine proteases), and in our case it would act as an inhibitor for the trypsin-like catalytic domain of serine protease HtrA1[1]-[3].
