Functions of the abl oncogene.

O N Witte

    Cancer Surveys
    |January 1, 1986

    Summary

    The abl oncogene encodes tyrosine kinase proteins implicated in cell growth. Research explores models for abl protein behavior in cellular transformation and leukemia, particularly in blood-forming cells.

    Area of Science:

    • Molecular Biology
    • Oncology
    • Cellular Biology

    Background:

    • The cellular abl oncogene and its viral counterparts encode tyrosine kinase proteins.
    • These proteins share similarities with the src gene family in their kinase activities.
    • Normal c-abl expression is widespread, but its role in blood cell growth regulation is a key focus.

    Purpose of the Study:

    • To explore recent data on the intracellular behavior of c-abl proteins.
    • To investigate models for abl protein function in cellular transformation and altered growth states.
    • To understand the specific structure-function relationships of abl proteins in hematopoietic cells.

    Main Methods:

    • Review of existing literature and recent data.
    • Analysis of in vitro and in vivo manifestations of tyrosine kinase activities.
    • Examination of the association of the abl oncogene with human chronic myelogenous leukemia.

    Main Results:

    • Abl proteins possess intrinsic tyrosine kinase activity, similar to the src gene family.
    • The murine v-abl protein exhibits a broad hematopoietic transformation spectrum.
    • The abl oncogene is linked to human chronic myelogenous leukemia.

    Conclusions:

    • Specific structure-function relationships of abl proteins may be critical for blood cell growth regulation.
    • Testable models are emerging for the intracellular behavior of c-abl proteins and their oncogenic forms.
    • Further research is needed to elucidate the precise mechanisms of abl in cellular transformation and disease.
