Anti-14-3-3 beta antibody

Supplementary info

Activity summary

14-3-3 beta also known as YWHAB is a protein that electrically neutralizes and stabilizes partner proteins. It has a mass of about 30 kDa and is part of the highly conserved 14-3-3 protein family. This family is ubiquitous in eukaryotic cells with 14-3-3 beta being expressed in many tissues including the brain and muscles. Its mechanical role involves binding phosphorylated serine and threonine residues which influences the conformation and function of the target protein.

Biological function summary

14-3-3 beta plays a central role in cellular processes like signal transduction apoptosis and cell cycle control. It often acts in concert with other proteins forming complexes that regulate these vital functions. For instance it binds to Raf-1 kinase affecting cell growth and differentiation. It also interacts with proteins involved in the mitogen-activated protein kinase (MAPK) pathway highlighting its diverse biological significance.

Pathways

14-3-3 beta is important in both the MAPK and apoptotic pathways. In the MAPK pathway it helps regulate the phosphorylation status of proteins involved in cell proliferation. The protein binds to Raf-1 an important component in MAPK signaling impacting cellular responses to growth signals. In the context of apoptosis 14-3-3 beta partners with BAD protein a pro-apoptotic factor sequestering it away from mitochondria this interaction is critical for cell survival by preventing the apoptotic process.

Associated diseases and disorders

Disruptions in 14-3-3 beta function associate with neurodegenerative diseases and cancer. For example its interaction with proteins like Tau connected to Alzheimer's disease points to its involvement in neurodegeneration. Aberrations in its regulatory roles can also contribute to uncontrolled cell growth linked to cancer. Furthermore its interaction with Bcl-2 family proteins ties it to variations in apoptotic regulation seen in cancerous cells.
