p50 is a protein that is part of the NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) transcription factor complex. NF-κB is a key regulator of immune responses, inflammation, and cell survival, and it plays a critical role in the development and progression of various types of cancer.
p50 is one of the two subunits of the NF-κB complex, the other being p65. The p50/p65 heterodimer is the most common form of NF-κB, and it is activated by a wide range of stimuli, including cytokines, growth factors, and stress.
In cancer, p50 is often overexpressed or constitutively activated, leading to the promotion of cell proliferation, survival, and metastasis.
