Activity summary

Platelet-derived growth factor AA or PDGF-AA is a member of the PDGF protein family which is involved in various cellular processes. The PDGF-AA protein has a molecular mass of approximately 24 kDa. It is expressed in a wide range of tissues including fibroblasts smooth muscle cells and neurons. The protein is considered a homodimer composed of two A chains and it plays an important role in cell signaling by binding to PDGF receptors on the surface of target cells.

Biological function summary

PDGF-AA influences cell proliferation migration and differentiation. It acts as a mitogen especially for mesenchymal cells such as fibroblasts and smooth muscle cells. PDGF-AA is often part of a signaling complex where it activates PDGF receptor-alpha (PDGFR-α) leading to autophosphorylation and subsequent activation of downstream effectors. This strengthens tissue development and wound healing processes.

Pathways

PDGF-AA integrates into critical signaling pathways like the PI3K/AKT pathway and the MAPK/ERK pathway. These pathways regulate cell growth and survival. PDGF-AA binds specifically to PDGFR-α which shares importance with other PDGF isoforms such as PDGF-BB in orchestrating cellular responses through similar pathways thereby ensuring precise physiological outcomes.

Associated diseases and disorders

PDGF-AA is implicated in conditions like cancer and fibrosis. Aberrant signaling involving PDGF-AA can lead to unchecked cell proliferation contributing to tumorigenesis. Similarly PDGF-AA is connected to fibrotic diseases where excessive tissue scarring occurs due to overactive fibroblast stimulation. PDGF-BB another member of the PDGF protein family often gets studied alongside PDGF-AA for their combined roles in these pathological states.
