What's a GeneRIF?

rChiA is a valuable molecule for further studies on structure-allergenicity relationships and as a tool for diagnosing allergies.
Title: Characterization of maize chitinase-A, a tough allergenic molecule.
Kinetic investigations indicate that the N-terminal carbohydrate-binding module (CBM) is not necessary for hydrolysis, and that the truncated chitinase A enzyme yields similar products to that of the full-length enzyme.
Title: Crystallographic structure of ChitA, a glycoside hydrolase family 19, plant class IV chitinase from Zea mays.
LH82 allele may be a specific genetic determinant that contributes to resistance to ear rot caused by Stenocarpella maydis whereas the B73 allele may contribute to susceptibility
Title: Allozyme-specific modification of a maize seed chitinase by a protein secreted by the fungal pathogen Stenocarpella maydis.

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.
