PACAPgene Pituitary adenylate cyclase-activating polypeptide (PACAP), often referenced simply as PACAP, stands as a remarkable polypeptide with a diverse and significant role in numerous physiological and pathological processes. This neuropeptide, encoded by the ADCYAP1 gene, has garnered considerable scientific attention due to its widespread distribution and potent biological activities. As a highly conserved neuropeptide, PACAP's functions extend across various species, making it a compelling subject for research in neuroendocrinology, developmental biology, and beyondPACAP-related Peptide (human) (trifluoroacetate salt).

First identified in the ovine hypothalamus for its ability to stimulate adenylate cyclase activity in rat anterior pituitary cells, PACAP was first identified as a 38aa peptide (PACAP-38). This initial discovery highlighted its considerable homology with vasoactive intestinal peptide (VIP), though PACAP 1-38 is a potent endogenous neuropeptide exhibiting even greater potency作者：ML Scaldaferri·2000·被引用次数：36—In this study, we provide evidence for the expression ofPACAPwithin rat and human placenta. We also demonstrate that both human and rat placenta express the .... The PACAP peptide exists primarily in two forms: PACAP-38 (a 38-amino acid form) and a shorter PACAP-27 form, both derived from a larger precursor molecule, preproPACAP. This structural characteristic underscores its nature as PACAP is a 38 amino acid polypeptidePACAP-Related Peptide (PRP), human是一种垂体腺苷酸环化酶激活肽(PACAP) 的前体蛋白，含有29 个氨基酸残基。- 高纯度，全球文献引用。.

The distribution of PACAP is extensive, reaching far beyond the pituitary gland. It is notably present in the brain, within the hypothalamic region, and has been demonstrated within the placenta in both rat and human studies.PACAP 1-38is a potent endogenous neuropeptide (IC 50 = 2 nM) showing considerable homology with vasoactive intestinal peptide (VIP) but with a greater potency. This broad presence suggests a critical involvement in various bodily functions, including neuroendocrine regulation, cellular development, and immune responses.PACAP-related peptide (PRP) is an endogenous 29-amino acid peptide that belongs to the secretin/glucagon superfamily of peptides, which includes secretin (Item ... Research indicates that PACAP increases the survival of cultured DRG neurons, with its effects comparable to those of nerve growth factor (NGF), further emphasizing its neurotrophic capabilitiesPituitary Adenylate Cyclase-Activating Polypeptide.

PACAP's involvement in neural tube expression during embryonic development highlights its role as an early inducer of cyclic adenosine monophosphate (cAMP) levels. This can influence cell proliferation and gene expression, playing a crucial role in developmental patterningPituitary Adenylate Cyclase-Activating Polypeptide. Beyond development, PACAP is implicated in regulating neuroendocrine and behavioral stress responses. Its presence in the gastrointestinal neuropeptide system also points to its involvement in digestive processes, placing it within the family of regulatory peptides that includes VIPPACAP 1-38 is a potent endogenous neuropeptide(IC 50 = 2 nM) showing considerable homology with vasoactive intestinal peptide (VIP) but with a greater potency..

Further research has elucidated the role of PACAP-Related Peptide (PRP), human, which is another peptide belonging to the secretin/glucagon superfamily. This PACAP-related peptide (PRP), containing 29 amino acids, also exhibits significant biological activityPituitary adenylate cyclase-activating polypeptide (PACAP) .... The interaction of PACAP with its receptors, particularly the PAC1 receptor (Pac1r), is fundamental to its signaling pathways.PACAP-Related Peptide (PRP), human The N-terminal EC domain of the PAC1 receptor has been shown to bind PACAP(6-38), with the PACAP peptide adopting a helical conformation when bound to hPAC1-R(S), including a bend at residue A18' and making extensive hydrophobic and electrostatic interactions.

The diverse functions of PACAP have led to investigations into its potential therapeutic applicationsPituitary Adenylate Cyclase-Activating Polypeptide in .... While not yet a mainstream therapeutic, the exploration of PACAP's role in conditions like migraine, and its potential as a target for drug development in relation to its subfamily of receptors, are active areas of research. The PACAP gene (ADCYAP1) has also been studied in the context of various diseases, including bladder cancer, where its methylation status may predict prognosis and influence the immune microenvironment.PACAP-related Peptide (human) (trifluoroacetate salt)
