Genes affected

DNAJC7 (HGNC:12392): (DnaJ heat shock protein family (Hsp40) member C7) This gene encodes a member of the DNAJ heat shock protein 40 family of proteins that is characterized by two N-terminal tetratricopeptide repeat domains and a C-terminal DNAJ domain. This protein binds the chaperone proteins heat shock proteins 70 and 90 in an ATP-dependent manner and may function as a co-chaperone. Pseudogenes of this gene are found on chromosomes 1 and 6. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Oct 2009]

NKIRAS2 (HGNC:17898): (NFKB inhibitor interacting Ras like 2) Predicted to enable GTPase activating protein binding activity. Predicted to be involved in I-kappaB kinase/NF-kappaB signaling. Predicted to act upstream of or within several processes, including Ral protein signal transduction; regulation of signal transduction; and surfactant homeostasis. Predicted to be located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
