    FAMILY
  • tachykinin family
  • CATEGORY signaling neurotransmitter , receptor
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • active peptides which excite neurons, evoke behavioral responses, are potent vasodilators and secretagogues,
  • and contract (directly or indirectly) many smooth muscles
  • possesses antiapoptotic effects in the colonic mucosa by activating AKT, which prevents apoptosis and mediates tissue recovery during colitis
  • centrally involved in gastric secretion, motility, mucosal immunity, and cell proliferation
  • playing a role in the regulation of platelet function
  • catabolized by degradative enzymes in tears to maintain the ocular surface by exerting the trophic effects of SP while avoiding undesirable effects
  • multipotent neuropeptide that affects the proliferation, activation and motility of keratinocytes and fibroblasts
  • TAC1/TACR1 system, leads to the activation of nuclear factor-kappa B (NFKB) and proinflammatory cytokines
  • role for TAC1/TACR1 interactions in adipose tissue responses, specifically as they relate to obesity-associated pathologies such as glucose intolerance and insulin resistance
  • upregulated monocyte tissue factor (TF), the major coagulation cascade stimulator, in a concentration and time dependent manner
  • beyond its neuroendocrine and inflammatory effects, could also be involved in targeting adipose tissue and influencing insulin resistance
  • promotes neurite outgrowth and the migration of pancreatic cancer cell cluster to the dorsal root ganglions

    protein
  • directly interact with P-glycoprotein as endogenous substrates for P-glycoprotein-mediated transport
  • ligand of TACR1
  • TAC1/TACR1 system is a major class 1, rhodopsin-like GPCR ligand-receptor interaction
  • TAC1/TACR1 interaction upregulates monocyte tissue factor
