  • GAA1 protein homolog
  • GAA1glycophosphatidylinositol anchor attachment 1
  • glycosylphosphatidylinositol anchor attachment protein 1 homolog (yeast)
  • GPAA1P anchor attachment protein 1 homolog (yeast)
  • GPAA1P anchor attachment protein 1 homolog
  • GPI anchor attachment protein 1

Background

The GPAA1 gene codes for a post-translational glycosylphosphatidylinositol (GPI) anchor attachment 1 protein at the GPI transfer step but is not essential for GPI synthesis. This protein functions as a general mechanism to link proteins to the cell surface membrane and is coded before/during the formation of the carbonyl intermediate. Isoform 1 is 621 amino acids in length at 67 kDA while isoform 2 exists at 561 amino acids long at 61 kDA. GPAA1 participates in various metabolic pathways as well as post-translational protein modification through interactions with genes PRR13, ALPP, PIN1, EIF3E, and GRIK5. GPAA1 has been investigated regarding various diseases such as ataxia, hepatocellular carcinoma, and breast cancer.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Peptides and proteins are guaranteed for 3 months from date of receipt.

Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
