Y chromosome
The Y chromosome is one of two sex chromosomes (allosomes) in mammals, including humans, and many other animals. The other is the X chromosome. Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that typically determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which by default triggers male development. The DNA in the human Y chromosome is composed of about 59 million
bone marrow cells were found to be presenting a peptide in the MHC groove encoded by a gene on Y chromosome. The peptide was foreign to the female T cells and females lack the Y chromosome and, thus, this MiHA. The MiHAs encoded by the Y chromosome are known as HY antigens.
H-Y Antigen.
H-Y antigens are encoded by genes on the Y chromosome. Both HLA class I and II alleles have been found to present these antigens. Some of these antigens are ubiquitiouly expressed in
