Automated description from the Alliance of Genome Resources (Release 8.3.0)
Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; cAMP response element binding activity; and cAMP response element binding protein binding activity. Contributes to DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including cellular response to leucine starvation; intracellular signal transduction; and regulation of gene expression. Acts upstream of or within several processes, including gluconeogenesis; positive regulation of macromolecule biosynthetic process; and positive regulation of sodium-dependent phosphate transport. Located in cytoplasm and nucleus. Part of ATF1-ATF4 transcription factor complex and ATF4-CREB1 transcription factor complex. Is expressed in several structures, including central nervous system; embryo ectoderm; eye; genitourinary system; and long bone. Human ortholog(s) of this gene implicated in prostate carcinoma. Orthologous to human ATF4 (activating transcription factor 4).
