Rabbit anti-Human NASP Polyclonal Antibody

Uniprot Id

P49321

Target Species

Human

Target Name

NASP

Target Full Name

Nuclear autoantigenic sperm protein

Target Function

Required for DNA replication, normal cell cycle progression and cell proliferation. Forms a cytoplasmic complex with HSP90 and H1 linker histones and stimulates HSP90 ATPase activity. NASP and H1 histone are subsequently released from the complex and translocate to the nucleus where the histone is released for binding to DNA.

Target Subcellular Location

Cytoplasm. Nucleus.

Target Protein Families

NASP family

Target Tissue Specificity

Isoform 1 is testis- and sperm-specific.

Target Background

This gene encodes a H1 histone binding protein that is involved in transporting histones into the nucleus of dividing cells. Multiple isoforms are encoded by transcript variants of this gene. The somatic form is expressed in all mitotic cells, is localized to the nucleus, and is coupled to the cell cycle. The testicular form is expressed in embryonic tissues, tumor cells, and the testis. In male germ cells, this protein is localized to the cytoplasm of primary spermatocytes, the nucleus of spermatids, and the periacrosomal region of mature spermatozoa.
