Protein dimers are common in catalysis and regulation. Their associations are either homodimers (identical monomers) or heterodimers (nonidentical monomers). The molecular principles of protein dimer interactions are difficult to understand mainly due to the geometrical and chemical characteristics of proteins.

Platelet Microtubule Subunit Proteins
Thrombosis and Haemostasis, 1977Microtubule subunit proteins have been isolated and purified from pig platelet homogenates and reassembled in vitro to form structures similar to those seen in the intact platelet. The major subunit protein tubulin has many of the properties of neurotubulin; it is a 6S dimer protein which binds colchicine and can be split into two non-identical ...

G protein subunits in lung cells
Life Sciences, 1994Many hormones and neurotransmitters bind to membrane-bound receptors that are coupled to signal generating enzymes or ion channels via signal transducing GTP-binding proteins termed G proteins. Although receptors and second messengers have been extensively studied in cells of the respiratory system, the G proteins responsible for the coupling of these ...

Subunit Composition of Lipoprotein(a) Protein
Biochemistry, 1994We determined the molecular weight of four different apo(a) polymorphs by sedimentation equilibrium in 6 M guanidine hydrochloride in order to estimate the molar ratio of apo(a) to apoB in Lp(a). They had molecular weights of 289,000, 310,000, 341,000, and 488,000 and 15, 16, 18, and 27 kringle 4 domains, respectively.

Subunit interactions of GTP‐binding proteins
European Journal of Biochemistry, 1992Fluorescence energy transfer [cf. Förster, T. (1948) Ann. Phys. 6, 55–75] was tested for its suitability to study quantitative interactions of subunits of Go with each other and these subunits or trimeric Go with the β1‐adrenoceptor in detergent micelles or after reconstitution into lipid vesicles [according to Feder, D., Im, M.‐J., Klein, H.

Proteins of Rabbit Reticulocyte Ribosomal Subunits
Nature, 1970BY comparison with those of prokaryotic cells, especially Escherichia coli, little is known about the ribosornes of eukaryotes. The present analysis of ribosomal proteins from rabbit reticulocytes indicates that—in spite of the larger size of the particle and a higher protein content—the number of different proteins is not significantly greater than ...
