What's a GeneRIF?

This study on N-terminally truncated beta-variants of the gastric H,K-ATPase provides direct evidence that the beta-N terminus assists in E2P state stabilization and that this is critical for the transport efficiency of the enzyme under in vivo conditions.
Title: E2P state stabilization by the N-terminal tail of the H,K-ATPase beta-subunit is critical for efficient proton pumping under in vivo conditions.
The substitution of 5 amino acids in the low affinity ouabain binding site of non-gastric proton-potassium exchanging ATPase in order to increase ouabain binding affinity is reported.
Title: Conversion of the low affinity ouabain-binding site of non-gastric H,K-ATPase into a high affinity binding site by substitution of only five amino acids.
Non-gastric H,K-ATPase is oligomycin-sensitive and can function as H+,NH4(+)-ATPase.
Title: The non-gastric H,K-ATPase is oligomycin-sensitive and can function as an H+,NH4(+)-ATPase.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
