General Comment NCBI Summary: 2,3-diphosphoglycerate (2,3-DPG) is a small molecule found at high concentrations in red blood cells where it binds to and decreases the oxygen affinity of hemoglobin. This gene encodes a multifunctional enzyme that catalyzes 2,3-DPG synthesis via its synthetase activity, and 2,3-DPG degradation via its phosphatase activity. The enzyme also has phosphoglycerate phosphomutase activity. Deficiency of this enzyme increases the affinity of cells for oxygen. Mutations in this gene result in hemolytic anemia. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Sep 2009]

Comment Maternal housekeeping proteins translated during bovine oocyte maturation and early embryo development. Massicotte L et al. Protein synthesis from maternal mRNA is needed to sustain oocyte maturation and embryo development prior to the maternal-embryonic transition (MET). Therefore, proteins that are expressed throughout this time are important and may be considered as maternal housekeeping proteins (MHKP). Our objectives were first, identify the translated protein patterns of bovine embryo development and secondly, determine the MHKP. Proteins synthesized during oocyte maturation and embryo development (2, 4 and 8-cell stages) were labeled using [S(35)]-Met and [S(35)]-Cys, and visualized by 2-DE. Embryos were cultured with alpha-amanitine to inhibit new transcription. Only 46 proteins were present throughout all stages. Ten spots were identified by MALDI-TOF and MS/MS: HSC71; HSP70; CypA; UCH-L1; GSTM5; Cct5; E-FABP; 2,3-BPGM, ubiquitin-conjugating enzyme E2D3; and beta-actin/gamma-actin. A new method called in silico protein identification confirmation was developed using EST databases. This method is a promising approach for use in rare tissue or from species with an incomplete protein database. This study has revealed that the translated protein patterns show a transition that brings the embryo to the MET. The needs in translated proteins between oocyte maturation and embryo development are different. In summary, this study represents the bases for future proteomics studies on bovine oocytes and embryos.
