    basic FUNCTION
  • acting as an inhibitor for transforming growth factor-beta (TGF-beta) signaling
  • T cell binding protein for the immunosuppressive agents FK506-rapamycin
  • intrinsic peptidyl-prolyl cis-trans isomerase activity
  • potential negative regulator of TGFBR endocytosis
  • modulating the release of calcium from the sarcoplasmic reticulum by RYR2
  • may be involved in neuronal or astrocytic cytoskeletal organization and in the abnormal metabolism of tau protein in AD damaged neurons
  • regeneration-associated gene in intrinsic CNS neurons
  • inhibitory function as an adaptor molecule for the SMAD7-SMURF1 complex to regulate the duration of the activin signal
  • regulates HRAS trafficking by promoting depalmitoylation through cis-trans isomerization of a peptidyl-prolyl bond in proximity to the palmitoylated cysteines
  • critical regulator of voltage-gated sodium current I(Na) and is important for cardiac arrhythmogenic physiology
  • forms an endogenous inhibitor of EGFR phosphorylation directly involved in the control of cellular EGFR activity
  • CELLULAR PROCESS protein, post translation, folding
    PHYSIOLOGICAL PROCESS immunity/defense
    text antipathogen response
    a component
    small molecule
  • modulating RYR1, RYR2 and RYR3
  • physically interacts and stabilizes RYR1 by decreasing channel open probability, playing the role for endogenous RYR stabilizer
  • binds to the glycine- and serine-rich motif (GS motif) of the TGF-beta type I receptor, and functions as a secure switch to prevent the leaky signal
  • bind to the skeletal muscle sarcoplasmic reticulum Ca2+ release channel [ryanodine receptor (RYR1)] and plays an important role in excitation-contraction coupling
  • interacted with another inhibitory molecule of activin signal, SMAD7, in an activin-dependent manner, and formed a complex with SMAD7 on the type I receptor
  • binds to HRAS in a palmitoylation-dependent fashion and promotes depalmitoylation
  • functionally interacts with EGFR (inhibit EGF-induced EGFR autophosphorylation with all internal phosphorylation sites equally affected)
  • interaction between FKBP1A and RYR1, RYR3 and ITPR1
  • promotes the RYR1 closed state, thereby inhibiting Ca2+ leakage in resting muscle
  • FKBP1A preferentially targets the BMP receptor ACVR1
