H1FNT explained

H1 histone family, member N, testis-specific is a member of the histone family of nuclear proteins which are a component of chromatin. In humans, this protein is encoded by the H1FNT gene.^[1]

The H1FNT protein is essential for nuclear formation in spermatozoa, and is involved in the replacement of histones with protamines during spermiogenesis.^[2]
