Abstract:
Membrane-tethered transcription factors (MTTFs) differ from cytosolic transcription factors (TF) in that they are innately membrane-bound. To attain TF activity, MTTFs are released from the membrane anchor as a result of proteolytic cleavage. This enables MTTFs to travel to the nucleus and modulate gene expression. Arabidopsis MTTFs characterized to date belong to either the bZIP or the NAC family. In this review, we highlight the most recent findings on Arabidopsis MTTFs that ascribe different yet important roles to these proteins: the MTTFs in the bZIP family appear to regulate stress signaling pathways, whereas members of the NAC family are involved in both development and stress response.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
