補足情報

This supplementary information is collated from multiple sources and compiled automatically.

Activin A also known by its gene name INHBA is a protein involved in various mechanical processes in the human body. This protein forms part of the transforming growth factor-beta (TGF-β) superfamily and has a molecular weight of approximately 25 kDa for its dimeric forms. Activin A is expressed in many tissues including the pituitary gland reproductive organs and placenta. Researchers often use techniques like the Activin A ELISA test kit to measure its concentration in biological samples.
Biological function summary

Activin A plays a significant role in regulating cell differentiation proliferation and apoptosis. As part of a complex Activin A interacts with specific receptors on cell surfaces initiating intracellular signaling cascades that influence these vital processes. It acts as a growth factor in the reproductive system influencing follicle-stimulating hormone (FSH) secretion and is important in embryonic development and wound healing.

Pathways

Activin A participates in pathways such as the TGF-β signaling pathway and the SMAD protein signaling pathway. Within these pathways it interacts with receptor proteins like type I and type II Activin receptors and downstream SMAD proteins. These interactions enable Activin A to regulate gene expression relevant to various cellular functions.

Altered Activin A levels have associations with conditions like cancer and fibrotic diseases. Its overexpression links to some cancer types including colorectal and prostate cancer where it influences tumor growth and metastasis. Moreover its interaction with proteins like myostatin may contribute to muscle wasting disorders. The dysregulation of these pathways highlights the significance of Activin A in pathophysiology.

機能

Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition.. Activin A is a homodimer of INHBA that plays a role in several essential biological processes including embryonic development, stem cell maintenance and differentiation, haematopoiesis, cell proliferation and tissue fibrosis (PubMed : 3194407, PubMed : 16440334). Signals through type I (such as ACVR1B or ACVR1C) and type II receptors (such as ACVR2A, ACVR2B or BMPR2) which, upon ligand binding, phosphorylate SMAD2 and SMAD3 intracellular signaling mediators that form a complex with SMAD4, translocate to the nucleus and modulate gene expression (PubMed : 10652306, PubMed : 24018044). Can also activate alternative non-canonical intracellular signaling pathways including the p38 MAPK, extracellular signal-regulated kinases 1/2 (ERK1/2) and c-Jun N-terminal kinases (JNKs) to modulate cell migration and differentiation (PubMed : 16440334). Alternatively, promotes osteoblastic differentiation via ACVRL1-SMAD1/5/9 pathway (PubMed : 34948289). In addition, can engage the type I receptor ACVR1 to form an ACVR1-activin A-type II receptor non-signaling complex (NSC) that renders receptors unavailable for engagement with BMPs, hence resulting in an apparent inhibition of ACVR1-mediated BMP signaling (PubMed : 26333933).. Inhibin A is a dimer of alpha/INHA and beta-A/INHBA that functions as a feedback regulator in the hypothalamic-pituitary-gonadal (HPG) axis. Inhibits the secretion of FSH from the anterior pituitary gland by acting on pituitary gonadotrope cells. Antagonizes activin A by binding to the proteoglycan, betaglycan, and forming a stable complex with and, thereby, sequestering type II activin receptors while excluding type I receptor.
