RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC STRAIN=N6; TISSUE=Oviduct;
RG NIH - Xenopus Gene Collection (XGC) project;
RL Submitted (SEP-2006) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Transcriptional activator. {ECO:0000250}.
CC -!- SUBUNIT: Binds DNA as a dimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Single-pass type II membrane protein {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Processed cyclic AMP-responsive element-binding
CC protein 3-like protein 4]: Nucleus {ECO:0000255|PROSITE-
CC ProRule:PRU00978}. Note=The cleaved N-terminal cytoplasmic domain
CC translocates into the nucleus. {ECO:0000250}.
CC -!- PTM: Controlled by regulated intramembrane proteolysis (RIP). A
CC fragment containing the cytoplasmic transcription factor domain is
CC released by proteolysis. The cleavage seems to be performed
CC sequentially by site-1 and site-2 proteases (PS1 and PS2) (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the bZIP family. ATF subfamily. {ECO:0000305}.
