Platelet-derived growth factor (PDGF) affects cell proliferation and differentiation during mammalian embryogenesis. In a number of avian species, PDGF-α receptors and PDGF-A chain (PDGF-A) are present during chicken limb and lens development. However, little is understood about the chicken PDGF-A gene. The present study identified short form type 1 (S1), long form (L) and short form type 2 (S2) cDNA...
The 20S proteasome is the proteolytic complex that is involved in removing abnormal proteins, and it also has other diverse biological functions. Its structure comprises 28 subunits arranged in four rings of seven subunits, and exists as a hollow cylinder. The two outer rings and two inner rings form an α7β7β7α7 structure, and each subunit, α and β, exists as seven different types, thus giving 14...
