Secreted Ly-6/uPAR-related protein 1 (SLURP1)

Has an antitumor action (PubMed:8742060). Was found to be a marker of late differentiation of the skin.

Implicated in keeping the physiological and structural integrity of the keratinocyte layers of the skin (PubMed:14721776, PubMed:17008884). In vitro down-regulates keratinocyte proliferation; the function may involve the projected role as modulator of nicotinic acetylcholine receptors (nAChRs) activity.
