The APCDD1 protein inhibits the Wnt signaling pathway and its mutations are associated with hereditary hypotrichosis simplex, causing hair loss. Increased expression of APCDD1 may be related to colorectal cancer development. The gene is highly expressed in the skin (RPKM 30.0), fat (RPKM 14.2), and 13 other tissues. APCDD1 Protein, Human (HEK293, Fc) is the recombinant human-derived APCDD1 protein, expressed by HEK293 , with C-hFc labeled tag.
