Divergence and functional degradation of a sex chromosome-like supergene (the sparrow with four sexes)
In January 2016, when the paper was published in Current Biology, it showed unequivocally that chromosome 2 was evolving like a sex chromosome. White–white and tan–tan matings were exceedingly rare. Using… Read more.

Interleukin-2-recptor alpha chain (IL2RA also called CD25) is the human protein encoded by the IL2RA gene.
The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while… Read more.
