Protein-coding gene in the species Homo sapiens
Spondin-1 (also known as F-spondin) is a protein that in humans is encoded by the SPON1 gene .[ 5] It is secreted by cells of the floor plate and may be involved in axon guidance [ 6] The protein contains 807 amino acids and is structurally composed of six thrombospondin domains, one reelin domain, and one spondin domain.
