The Myc Transcription
Factor
By: Michael Reisfeld
MYC Was Originally cloned
From a transforming Virus
Myc is a Transcription Factor Which
Dimerizes With a Leucine Zipper and
binds to DNA Via a Helix-Loop-Helix
Myc is part of pathway that
promotes Cell Proliferation
Myc Targets a Huge Array of
Genes to Perform This Function
Myc is a Family
of Three
Proteins, in
Which Each
Possesses a
Slightly
different
Function
Overexpression of Each Specific Myc Protein Is
Responsible for Corresponding Tumor Types
Neuroblastoma (N-myc)
Burkitt’s Lymphoma (c-myc)
Small Cell Lung Cancer (L-myc)
c-Myc Overexpression Can Induce
Tumors
A More
Human
Side…
Burkitt’s Lymphoma
• 2% of Lymphoproliferative Disorders
• C-myc translocation associated with ALL cases
– 85% involve translocation to IGH
Is Myc a Viable Target for
Treatment?
