Rabbit anti-Human GIMAP5 Polyclonal Antibody

Uniprot Id

Q96F15

Target Species

Human

Target Name

GIMAP5

Target Full Name

GTPase IMAP family member 5

Target Function

Plays a role in T lymphocyte development and the optimal generation of CD4/CD8 double-positive thymocytes. Inhibitor of GSK3A, possibly by sequestering GSK3A in cytoplasmic vesicles and impairing its translocation to the nucleus. Consequently, impairs GSK3A-dependent transcriptional program and regulation of the DNA damage response occurring during T cells proliferation. Required for the survival of peripheral T cells, natural killer (NK) and NK T-cell development and the maintenance of normal liver function. May promote the survival of mature T lymphocytes upon cytokine withdrawal. May regulate Ca(2+) homeostasis by modulating lysosomal Ca(2+) stores, preventing its accumulation in the absence of T cell activation. May play a role in mitochondrial DNA segregation in hematopoietic tissues.

Target Subcellular Location

Lysosome membrane; Single-pass type IV membrane protein. Endosome, multivesicular body membrane; Single-pass type IV membrane protein. Endosome membrane; Single-pass type IV membrane protein.

Target Protein Families

TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily, AIG1/Toc34/Toc159-like paraseptin GTPase family, IAN subfamily

Target Tissue Specificity

Widely expressed with high levels in lymph node and spleen. High expression found in T lymphocytes, including CD4 and CD8-positive T-cells, and monocytes. Very low expression levels in B-lymphocytes.

Target Background

This gene encodes a protein belonging to the GTP-binding superfamily and to the immuno-associated nucleotide (IAN) subfamily of nucleotide-binding proteins. In humans, the IAN subfamily genes are located in a cluster at 7q36.1. This gene encodes an antiapoptotic protein that functions in T-cell survival. Polymorphisms in this gene are associated with systemic lupus erythematosus. Read-through transcription exists between this gene and the neighboring upstream GIMAP1 (GTPase, IMAP family member 1) gene.
