Genes affected

GIMAP1 (HGNC:23237): (GTPase, IMAP family member 1) 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 is thought to be involved in the differentiation of T helper (Th) cells of the Th1 lineage, and the related mouse gene has been shown to be critical for the development of mature B and T lymphocytes. Read-through transcription exists between this gene and the downstream GIMAP5 (GTPase, IMAP family member 5) gene. [provided by RefSeq, Dec 2010]

GIMAP1 links:

GIMAP1-GIMAP5 (HGNC:51257): (GIMAP1-GIMAP5 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring GIMAP1 (GTPase, IMAP family member 1) and GIMAP5 (GTPase, IMAP family member 5) genes on chromosome 7. Alternative splicing results in multiple readthrough transcript variants, one of which encodes a fusion protein that shares sequence identity with each individual gene product.
