Characterization of HMG2 complement changes in chicken tissues.
Variations in the content of nonhistone proteins high mobility group 2a (HMG2a) and HMG2b have been determined in several cell types of chicken. HMG2a was found to accumulate during erythrocyte maturation. HMG2b is the major HMG2 subtype in testis and reaches the highest proportion, detected so far, in spermatid cells obtained by centrifugal elutriation. In hepatocytes HMG2b is barely detectable and HMG2a is the major subtype. In conclusion, the pattern of HMG2 composition is different in three quiescent and terminally differentiated cell types, no correlation between the state of cell proliferation and HMG2 composition can be established.
