This affinity-purified antibody is directed against phosphorylated human HMGN protein at pS20 and pS24 residues (other HMGN proteins have this conserved sequence but at other residue positions). Reactivity occurs against human HMGN pS20/pS24 proteins and the antibody is specific for the phosphorylated form of the proteins. Reactivity is seen against HMGN1 and HMGN2. HMGN3 is also likely reactive although not tested. Reactivity with non-phosphorylated human HMGNs is minimal by ELISA. A BLAST analysis was used to suggest cross reactivity with HMGN proteins from Xenopus, chicken, mouse, bovine, dog, orangutan, rat and swine based on 100% homology with the immunizing sequence. Reactivity against homologues from other sources is not known.
The high-mobility group (HMG) proteins 14 and 17 are abundant chromosomal proteins that bind to nucleosomes and enhance transcription. HMG-14 and HMG-17 also function as architectural elements, which alter the structure of the chromatin fiber and enhance transcription from chromatin templates. HMG-14/17 proteins modify the nucleosomal organization of the 30 nm chromatin fiber and mediate the unfolding of the higher order chromatin structure thereby facilitating access to the underlying DNA sequence. Clustering of architectural elements, such as HMG proteins and linker histone subtypes into distinct domains, may lead to structural and functional heterogeneity along the chromatin fiber. In addition, HMG-14 and HMG-17 have been identified as constitutive components of mouse oocyte and embryonic chromatin that establish a link between the structure of embryonic chromatin and the normal progression of embryonic development.
