 The calculated theoretical pI of this protein is 6.07.Proteasome subunit beta type-10 is one of the 17 essential subunits (alpha subunits 1-7, constitutive beta subunits 1-7, and inducible subunits including beta1i, beta2i, beta5i) that contributes to the complete assembly of 20S proteasome complex.In particular, proteasome subunit beta-2i, along with other beta subunits, assemble into two heptameric rings and subsequently a proteolytic chamber for substrate degradation.
