Epigenetics
E3 ubiquitin-protein ligase UBR4 is an enzyme that is encoded by the UBR4 gene.The protein encoded by this gene is an E3 ubiquitin-protein ligase that interacts with the retinoblastoma-associated protein in the nucleus and with calcium-bound calmodulin in the cytoplasm. The encoded protein appears to be a cytoskeletal component in the cytoplasm and part of the chromatin scaffold in the nucleus.Diseases associated with UBR4 include Alternating Hemiplegia Of Childhood 2 and Long Qt Syndrome. Among its related pathways are Class I MHC mediated antigen processing and presentation and Innate Immune System.
As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.
