Promotion of cell cycle progression by basic helix-loop-helix E2A.
Normal B-cell development requires the E2A gene and its encoded transcription factors E12 and E47. Current models predict that E2A promotes cell differentiation and inhibits G(1) cell cycle progression. The latter raises the conundrum of how B cells proliferate while expressing high levels of E2A protein. To study the relationship between E2A and cell proliferation, we established a tissue cult...
متن کاملE2A basic helix-loop-helix transcription factors in human leukemia.
The gene E2A on chromosome 19 is involved in recurrent chromosomal rearrangements associated with pediatric acute lymphoblastic leukemia. The resulting fusion of 5' E2A sequences with 3' portions of other genes leads to the expression of two well-characterized fusion proteins: E2A-PBX1 and E2A-HLF. Since the E2A, PBX1 and HLF proteins all appear to function as transcription factors, it appears ...
متن کاملCell-specific expression of helix-loop-helix transcription factors encoded by the E2A gene.
The E2A gene encodes transcription factors of the helix-loop-helix family that are implicated in cell-specific gene expression as part of dimeric complexes that interact with E box enhancer elements. It has previously been shown that transcripts of the E2A gene can be detected in a wide range of cell types. We have now examined expression of the mouse E2A gene at the protein level using polyclo...
متن کاملE2A basic-helix-loop-helix transcription factors are negatively regulated by serum growth factors and by the Id3 protein.
Id3, a member of the Id multigene family of dominant negative helix-loop-helix transcription factors, is induced sharply in murine fibroblasts by serum growth factors. To identify relevant targets of Id3 activity, the yeast two-hybrid system was used to identify proteins that dimerize with Id3. Four murine cDNAs were identified in the screen, all of which encode helix-loop-helix proteins: E12, ...
متن کاملBasic helix-loop-helix proteins E2A and HEB induce immature T-cell receptor rearrangements in nonlymphoid cells.
T-cell receptor (TCR) gene rearrangements are mediated via V(D)J recombination, which is strictly regulated during lymphoid differentiation, most probably through the action of specific transcription factors. Investigated was whether cotransfection of RAG1 and RAG2 genes in combination with lymphoid transcription factors can induce TCR gene rearrangements in nonlymphoid human cells. Transfectio...
