Function. The product of this gene belongs to the integrin alpha chain family of proteins. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain.. The top two points seem fine, no problems there. Not sure entirely what context this is being used in - what level are you studying at? Your working for the (alpha + beta)^3 seems to be correct as well, if that's all you are trying to show.. Distribution of alpha 2, alpha 3, alpha 4, and beta 2 neuronal nicotinic receptor subunit mRNAs in the central nervous system: a hybridization histochemical study in the rat. On Solve This Sum, you can find solutions of maths sums of almost every kind, from every topic, browse through a collection of maths problems of higher secondary and above level and for various entrance examinations.. im not sure exactly what you mean. for the equation x^4 - a^4 the roots are a, -a, ia, -ia. Of course, without knowing the roots, we know that the sum of all of them is zero, as is the sum of double products, triple products, and product of all 4 is -a^4..
