Cellular location of functioncytoplasm
Commentsupregulation of LDH seen in some cancers, but not clear which function (or both) involved
Function 2
Function descriptionRNA binding protein, post-transcriptional regulation of gene expression, AU-rich element (ARE, binding to these kinds of elements can be involved in affecting RNA stability) binding protein (AUBP), role may also involve binding to AUF1 protein, binds the 3 -UTR of GM-CSF RNA

E.C. number
Location of functional site(s)Rossman fold also involved in this function, so probably cannot perform both functions simultaneously, binding to RNA competed by NAD+
