Thymulin (also known as thymic factor or its old name facteur thymique serique) is a nonapeptide produced by two distinct epithelial populations in the thymus first described by Bach in 1977. It requires zinc for biological activity. Its peptide sequence is H-Pyr-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH.
