Gene Information
human ... TNP1(7141)
General description
TNP1 (transition protein 1) gene also referred to as TP1 encodes a 54 amino acids containing nuclear protein that belongs to nuclear transition protein 1 family. It is a spermatid-specific product of the haploid genome which replaces histone and is itself replaced in the mature sperm by the protamines. It is also a basic protein well conserved in mammalian species. It has a role in spermiogenesis. Mutation in TNP1 gene leads to male infertility.
Immunogen
Synthetic peptide directed towards the N terminal region of human TNP1
Application
Anti-TNP1 antibody produced in rabbit is suitable for western blotting at a concentration of 1μg/mL.
Biochem/physiol Actions
In mammals, the second stage of spermatogenesis is characterised by the conversion of nucleosomal chromatin to compact, non-nucleosomal and transcriptionally inactive form found in sperm nucleus. This condensation is associated with a double-protein transition. The first transition corresponds to the replacement of histones by several spermatid-specific proteins (also called transition proteins) which are themselves replaced by protamines during the second transition. 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.

The ram transition protein 1 (TP1) is present in spermatid cell nuclei in the nonphosphorylated, monophosphorylated and diphosphorylated forms. Its primary structure was determined by automated Edman degradation of S-carboxamidomethylated protein and of peptides generated by cleavage with thermolysin and

The gene for mouse transition protein 1 (mTP1) was isolated, sequenced, and chromosomally mapped. The nucleotide sequence of 1895 bp of a 6.4-kb mTP1 genomic subclone was determined to include 788 bp of 5' flanking region, 564 bp of coding
