Genes affected

TWF1 (HGNC:9620): (twinfilin actin binding protein 1) This gene encodes twinfilin, an actin monomer-binding protein conserved from yeast to mammals. Studies of the mouse counterpart suggest that this protein may be an actin monomer-binding protein, and its localization to cortical G-actin-rich structures may be regulated by the small GTPase RAC1. [provided by RefSeq, Jul 2008]

TWF1 links:

TMEM117 (HGNC:25308): (transmembrane protein 117) Involved in intrinsic apoptotic signaling pathway in response to endoplasmic reticulum stress. Located in endoplasmic reticulum and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

TMEM117 links:

IRAK4 (HGNC:17967): (interleukin 1 receptor associated kinase 4) This gene encodes a kinase that activates NF-kappaB in both the Toll-like receptor (TLR) and T-cell receptor (TCR) signaling pathways. The protein is essential for most innate immune responses. Mutations in this gene result in IRAK4 deficiency and recurrent invasive pneumococcal disease. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]
