Summary: Enables dihydrofolate reductase activity. Acts upstream of or within folic acid metabolic process; heart contraction; and heart development. Predicted to be active in mitochondrion. Is expressed in several structures, including anterior neural tube; hematopoietic system; immature eye; nervous system; and neural plate. Human ortholog(s) of this gene implicated in acute lymphoblastic leukemia. Orthologous to human DHFR (dihydrofolate reductase) and DHFR2 (dihydrofolate reductase 2).

What's a GeneRIF?

In the current study, we observed the effect of chemical chaperones from four different classes on the stability and functionality of aggregation prone protein zebrafish dihydrofolate reductase
Title: Quantification of differential efficacy of chemical chaperones in ameliorating solubilization and folding of zebrafish dihydrofolate reductase.
The heat induced inactivation of DHFR follows first-order kinetics and Arrhenius law. The variation in the value of inactivation rate constant k with increasing temperatures depicts faster inactivation at elevated temperatures. Attempted to study the chaperoning ability of a shorter variant of GroEL (minichaperone) and compared it with that of conventional GroEL-GroES chaperone system.
Title: Kinetics and thermodynamics of the thermal inactivation and chaperone assisted folding of zebrafish dihydrofolate reductase.
A comparative study of various species of DHFR shows that zDHFR has comparable thermodynamic stability with human counterpart and thus proved to be a good in vitro model system for structure- function relationship studies.
Title: Investigation of folding unfolding process of a new variant of dihydrofolate reductase protein from Zebrafish.

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.
