p62 in Cancer: Signaling Adaptor Beyond Autophagy.
Review
Overview
abstract
Adaptor proteins participate in selective autophagy, which is critical for cellular detoxification and stress relief. However, new evidence supports an autophagy-independent key role of the adaptor p62 (encoded by the gene Sqstm1) in signaling functions central to tumor initiation in the epithelium and suppression of tumor progression in the stroma.
