This gene encodes a protein belonging to the GTP-binding superfamily and to the immuno-associated nucleotide (IAN) subfamily of nucleotide-binding proteins. The encoded protein of this gene may be negatively regulated by T-cell acute lymphocytic leukemia 1 (TAL1). In humans, the IAN subfamily genes are located in a cluster at 7q36.1. GIMAP4 (GTPase, IMAP Family Member 4) is a Protein Coding gene. Diseases associated with GIMAP4 include T-Cell Acute Lymphocytic Leukemia-1 and Behcet Syndrome. GO annotations related to this gene include GTP binding. An important paralog of this gene is GIMAP7.
