function:In the elongating spermatids of mammals, the conversion of nucleosomal chromatin to the compact, non-nucleosomal form found in the sperm nucleus is associated with the appearance of a small set of basic chromosomal transition proteins.,similarity:Belongs to the nuclear transition protein 2 family.,tissue specificity:Testis.,
Nucleus . Chromosome . Loaded onto the nucleosomes of condensing spermatids (By similarity). Nuclear import is ATP-dependent and nucleolar localization requires the protein to be phosphorylated (By similarity). .
Expressed by spermatids (at protein level).
