[Empirical construction of the evolutionary divergence tree of VH-genes of immunoglobulins in mouse family 36-60].

Formerly unknown variable gene of the heavy chain of immunoglobulin (VHTF) was studied in our preceding works in detail. In this paper, we present the results of defining the structure of N-terminus of the heavy chain which confirm the presence of unusual first codon corresponding to threonine. The structure of the VHTF gene is being compared with that of other genes of the 36-60 family, topology of the tree of their evolutionary divergence is being established with the help of empirical algorithm. Its advantages, as compared with the conventional methods, are under discussion.
