TranscriptomicsCharacterization of a P-REX1 gene signature in breast cancer cells
The Rac nucleotide Exchange Factor (Rac-GEF) P-Rex1 is highly expressed in breast cancer, specifically in the luminal subtype, and is an essential mediator of actin cytoskeleton reorganization and cell migratory responses induced by ErbB and other tyrosine-kinase receptors. Heregulin, a growth facto...

ProteomicsStructure of the metastatic factor P-Rex1 reveals a two-layered autoinhibitory mechanism
Rho GTPases regulate actin dynamics and cell motility, and their hyperactivation drives cancer metastasis1. P-Rex (PI(3,4,5)P3-dependent Rac Exchanger) guanine nucleotide exchange factors (GEFs) are potent on-switches for Rho GTPase signalling and are frequently dysregulated in metastatic cancer2. P...

GenomicsChIP-sequencing (ChIP-seq) experiments on female ESCs expressing V5-tagged REX1 and control wild-type Embryonic stem cells (ESCs)
Evolution of the mammalian sex chromosomes has resulted in a heterologous X and Y pair, where the Y chromosome has lost most of its genes. Hence, there is a need for X-linked gene dosage compensation between XY males and XX females. In placental mammals, this is achieved by random inactivation of on...

ProteomicsREX1 is the critical target of RNF12 in imprinted X chromosome inactivation in mice.
In mice, imprinted X-chromosome inactivation (iXCI) of the paternal X in the pre-implantation embryo and extra-embryonic tissues is followed by X-reactivation in the epiblast precursors of the inner cell mass (ICM) of the blastocyst, to facilitate initiation of random XCI (rXCI) in all embryonic tis...

TranscriptomicsTransition of embryonic stem cells from ground state pluripotency
Mouse embryonic stem cells were maintained in minimal and chemically-defined culture conditions supporting naive pluripotency. Inhibitors of the Gsk3 (CHIR99021) and Mek/Erk (PD0325901) pathways were withdrawn, cultures maintained for 24 hours, and subsequently sorted by flow cytometry based on fluo...

TranscriptomicsRex1/Zfp42 is dispensable for pluripotency in mouse ES cells
We showed the function of Rex1 in mouse ES cells as well as in embryos using the conventional gene targeting strategy. Our results clearly indicated that Rex1 function is dispensable for both the maintenance of pluripotency in ES cells and the development of embryos. However, Rex1-/- ES cells showed...

ProteomicsThe pseudokinase NRBP1 activates Rac/Cdc42 via P-Rex1 to drive oncogenic signalling in triple negative breast cancer
In an effort to identify oncogenic protein kinase drivers in triple negative breast cancer (TNBC), we undertook mass spectrometry (MS)-based proteomic profiling across a large panel of TNBC cell lines. This revealed marked variation in expression of the multidomain pseudokinase Nuclear Receptor Bind...
