Heterodimers

... that later associate to form dimers. If you look at it as a pseudo-Punnet square, then 25% of the dimers are of each homodimer and 50% are heterodimers (alpha associates with beta or beta associates with alpha). There are four possible associations, two of them are the same heterodimer, ...

... them alpha and beta. If all types of dimers are equally likely, there are three types of dimers possible: pure alpha, pure beta and alpha-beta heterodimers. If each are equally likely, then 33.3% of the mixture should be represented by each type of dimer. I guess you can argue there are five ...

If we want we can all add things: For example: microtubules are composed of tubulin which is composed of 2 heterodimers: alpha-tubulin and beta-tubulin that takes place at low calcium concentrations and is facilitated by some microtubule associated proteins. Other microtubule ...
