Content of the Hmg-17 Chromosomal Protein in Porcine Tissues

HMG-17 proteins are nucleosomal proteins, implicated in control of chromatin structure and transcription, in a way that has not yet been fully understood. In this report, quantification of HMG-17 in porcine tissues was performed, by ELISA, using previously produced and characterized specific rabbit anti- HMG-17 antibodies. Our results showed high levels of HMG-17 compared to the DNA and H1 content of the tissues (on the contrary to previous reports), and more specifically that there were 1.7 molecules of HMG-17 per molecule of histone H1.
