NCBI and Uniprot Product Information
Uniprot Description
Alpha subunit of the heterotrimeric guanine nucleotide-binding protein (G protein) that mediates mating pheromone signal transduction. Binding of alpha-factor or a-factor to its cognate transmembrane receptor STE2 and STE3, respectively, allows the receptor to serve as a guanine nucleotide exchange factor (GEF) on GPA1. The exchange of GDP for GTP on the G protein alpha subunit alters its interaction with the G protein beta subunit STE4, leading to dissociation of the G protein beta-gamma dimer STE4-STE18. The dissociated subunits activate downstream effectors to activate the mating response pathway and induce changes necessary to produce mating-competent cells. STE4-STE18 activate the downstream pheromone signaling MAP kinase cascade leading to expression of mating-specific genes, inducing cell cycle arrest in G1, promoting polarized cell growth to form mating projections (shmoos), and establishing the changes in plasma membrane, cell wall and nuclear envelope to permit cell-cell fusion (plasmogamy) and fusion of the two haploid nuclei (karyogamy). GPA1 transmits a signal that requires direct binding to the effector enzyme PI3K located at the endosome, promoting increased PI3 production. The intrinsic GTPase activity of GPA1 determines the duration of signaling, and is dramatically accelerated by the RGS protein SST2. In unstimulated cells, GDP-bound GPA1 sequesters the G protein beta-gamma subunit STE4-STE18, preventing it from activating the downstream effectors. Also down-regulates the signal by inhibiting the pheromone-induced accumulation of FUS3 in the nucleus.

Product Notes
The GPA1 gpa1 (Catalog #AAA7164785) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Rabbit anti-Saccharomyces cerevisiae (strain ATCC 204508/S288c)(Baker's yeast) GPA1 Polyclonal Antibody reacts with Saccharomyces cerevisiae (strain ATCC 204508/S288c)(Baker's yeast) and may cross-react with other species as described in the data sheet. AAA Biotech's GPA1 can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA), WB (Western Blot) (ensure identification of antigen). Researchers should empirically determine the suitability of the GPA1 gpa1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "GPA1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
