Activin A receptor type IB (ACVR1B), also known as ALK4. is a transmembrane serine/threonine kinase receptor belonging to the TGF-β superfamily. It plays a critical role in mediating signaling pathways initiated by activins, growth differentiation factors (GDFs), and nodal ligands. Upon ligand binding, ACVR1B forms a complex with type II receptors, leading to phosphorylation of intracellular SMAD2/3 proteins. These activated SMADs translocate to the nucleus to regulate gene expression involved in cell proliferation, differentiation, apoptosis, and immune responses.
ACVR1B is essential during embryonic development, particularly in mesoderm formation and left-right patterning. Dysregulation of ACVR1B signaling has been implicated in pathologies such as cancer, fibrosis, and reproductive disorders. For example, aberrant activation promotes tumor progression and metastasis in certain cancers, while loss-of-function mutations may disrupt tissue homeostasis.
Antibodies targeting ACVR1B are vital tools for studying its expression, localization, and signaling mechanisms. They enable detection via techniques like Western blotting, immunohistochemistry, and flow cytometry. Additionally, therapeutic antibodies or inhibitors against ACVR1B are under exploration to modulate its activity in diseases like myelofibrosis or pancreatic cancer. Research continues to unravel its context-dependent roles and therapeutic potential, emphasizing its dual function as both a tumor suppressor and oncogenic driver in different cellular environments.
