Functional Description

Binds ATP, opioids and phosphatidylethanolamine. Has lower affinity for phosphatidylinositol and phosphatidylcholine. Serine protease inhibitor which inhibits thrombin, neuropsin and chymotrypsin but not trypsin, tissue type plasminogen activator and elastase (By similarity). Inhibits the kinase activity of RAF1 by inhibiting its activation and by dissociating the RAF1/MEK complex and acting as a competitive inhibitor of MEK phosphorylation.

REGION 93 134 Interaction with RAF1.
MOD_RES 42 42 Phosphothreonine.
MOD_RES 52 52 Phosphoserine.
MOD_RES 54 54 Phosphoserine (By similarity).
