msl-1 | Protein male-specific lethal-1; The Msl proteins are essential for elevating transcription of the single X chromosome in the male (X chromosome dosage compensation). Msl-1 is a pioneer protein. Mle, msl-1 and msl-3 are colocalized on the X chromosome. Each of the MSL proteins requires all the other MSLs for wild-type X-chromosome binding. In complex with msl-2, promotes ubiquitination of histone H2B. (1039 aa) | ||||
Ire1 | Inositol-requiring enzyme-1 (Ire1) encodes a transmembrane protein that mediates the unfolded protein response. Misfolded peptides in the endoplasmic reticulum activate the RNase activity of the product of Ire1, thereby promoting the cleavage of its downstream substrates, such as Xbp1 mRNA. The product of Ire1 is also required for photoreceptor differentiation. (1074 aa) |
