About GPAA1

Cytogenetic location: 8q24.3 Genomic coordinates (GRCh38): 8:144,082,634-144,086,216 (from NCBI)

This gene has 72 transcripts (splice variants), 195 orthologues and is associated with 3 phenotypes. Ubiquitous expression in kidney (RPKM 27.5), thyroid (RPKM 25.6) and 25 other tissues.

Summary

Posttranslational glycosylphosphatidylinositol (GPI) anchor attachment serves as a general mechanism for linking proteins to the cell surface membrane. The protein encoded by this gene presumably functions in GPI anchoring at the GPI transfer step. The mRNA transcript is ubiquitously expressed in both fetal and adult tissues. The anchor attachment protein 1 contains an N-terminal signal sequence, 1 cAMP- and cGMP-dependent protein kinase phosphorylation site, 1 leucine zipper pattern, 2 potential N-glycosylation sites, and 8 putative transmembrane domains.
