We have cloned the alpha-agglutinin structural gene, AG alpha 1, by the isolation of alpha-specific agglutination-defective mutants, followed by isolation of a complementing plasmid. Independently isolated alpha-specific agglutination-defective mutations were in a single complementation group, consistent with biochemical results indicating that the alpha-agglutinin is composed of a single polypeptide. Mapping results suggested that the complementation group identified by these mutants is allelic to the ag alpha 1 mutation identified previously. Expression of AG alpha 1 RNA was alpha specific and inducible by a-factor. Sequences similar to the consensus sequences for positive control by MAT alpha 1 and pheromone induction were found upstream of the AG alpha 1 initiation codon. The AG alpha 1 gene could encode a 650-amino-acid protein with a putative signal sequence, 12 possible N-glycosylation sites, and a high proportion of serine and threonine residues, all of which are features expected for the alpha-agglutinin sequence. Disruption of the AG alpha 1 gene resulted in failure to express alpha-agglutinin and loss of cellular agglutinability in alpha cells. An Escherichia coli fusion protein containing 229 amino acids of the AG alpha 1 sequence was recognized by an anti-alpha-agglutinin antibody. In addition, the ability of this antibody to inhibit agglutination was prevented by this fusion protein. These results indicate that AG alpha 1 encodes alpha-agglutinin. Features of the AG alpha 1 gene product suggest that the amino-terminal half of the protein contains the a-agglutinin binding domain and that the carboxy-terminal half contains a cell surface localization domain, possibly including a glycosyl phosphatidylinositol anchor.

We have previously described a myoblast cell surface glycoprotein of the molecular mass 46 000 (gp46), which is associated with myoblast differentiation. In this report we demonstrate that gp46 binds specifically to gelatin-Sepharose and in this respect is similar to a glycoprotein of the molecular mass 47 000, which has earlier been described as a cell surface localized protein in mouse parietal endoderm cells and in chick embryo fibroblasts. To ascertain the relationship of gp46 to myoblast differentiation, wild-type L6 myoblasts, as well as two concanavalin A (ConA) resistant, differentiation-negative, myoblast mutants (D-1 and C-8), were examined for gp46 expression. In the mutant designated D-1, which has a defect in dolichol mannosyl transferase, both mannose incorporation into gp46 and ConA binding to gp46 was reduced compared with L6, without markedly affecting the gelatin adhesion properties of gp46. Western blotting with a monoclonal antibody against gp46 was used to show that the expression of gp46 was normal in D-1 but was reduced in mutant C-8 compared with L6. Reduction occurred both in the plasma membrane and endoplasmic reticulum fractions of C-8 compared with wild-type L6. In L6 myoblasts, the expression of gp46 remained constant during myoblast replication and fusion but decreased markedly postfusion. In the nonfusing myoblast mutants D-1 and C-8 and in wild-type L6 cells that were prevented from fusing by treatment with 5-bromo-2′-deoxyuridine, the expression of gp46 remained invariant. We suggest that collagen interactions, mediated by gp46, are important for normal rat skeletal muscle differentiation.
