The unfolded protein response (UPR) is a conserved signalling pathway activated on the accumulation of unfolded proteins within the endoplasmic reticulum (ER), termed ER stress. Upon ER stress, HAC1/XBP1 undergoes exon/intron-specific excision by inositol requiring enzyme 1 (IRE1) to remove an intron and liberate the 5' and 3' exons. In yeast, the 5' and 3'(More)
Transcription of the human fetal globin genes in erythroid cells is tightly regulated during different stages of development and differentiation. Two naturally occurring mutations 202 base pairs upstream of the duplicated gamma globin genes are associated with incorrectly regulated gamma globin gene gene expression; elevated levels of fetal globin are(More)
The quantitative tissue specificity of the high mobility group (HMG) chromosomal proteins was investigated. Perchloric acid (PCA) extracts of four different chicken tissues and erythrocytes contained three proteins which comigrated on NaDodSO4-polyacrylamide gels with the HMG's 1,2, and E from erythrocyte nuclei. These three HMG's from embryonic skeletal(More)
