Granulins

**Definition:** Small, cysteine-rich peptides generated by the proteolytic cleavage of progranulin. Granulin peptides are each composed of a granulin-motif, while paragranulin is composed of a half-granulin motif. The mammalian granulins are named granulin 1-7 for their sequence order in the progranulin propeptide, and are alternately named granulin G, F, B, A, C, D, and E; or epithelin 7, 6, 2, 1, 3, 4, and 5, i.e. granulin 1 aka granulin G aka epithelin 7, etc.
