P21

Evidence summary pending

This topic is on our research list. Its full evidence and safety summary has not been completed.

Identity and scope

P21 alone is ambiguous. A relevant original paper identifies a modified CNTF-related compound as Peptide 021 (P021); this spelling resemblance is not enough to identify the present listing. Confirm the full name, sequence and terminal modifications before assigning P021 findings. Research on the cell-cycle protein p21 is a different subject.

Original P021 cell and mouse study ↗ — This source names Peptide 021 (P021), a modified CNTF-related compound. It does not establish that an unspecified P21 listing contains that preparation.
