IVNS1ABP

IVNS1ABP (Influenza Virus NS1A Binding Protein) is a Protein Coding gene. Diseases associated with IVNS1ABP include Influenza and Dengue Disease. Among its related pathways are Influenza A. An important paralog of this gene is KLHL26.

Full Name

IVNS1ABP

Function

Involved in many cell functions, including pre-mRNA splicing, the aryl hydrocarbon receptor (AHR) pathway, F-actin organization and protein ubiquitination. Plays a role in the dynamic organization of the actin skeleton as a stabilizer of actin filaments by association with F-actin through Kelch repeats (By similarity).
Protects cells from cell death induced by actin destabilization (By similarity).
Functions as modifier of the AHR/Aryl hydrocarbon receptor pathway increasing the concentration of AHR available to activate transcription (PubMed:16582008).
In addition, functions as a negative regulator of BCR(KLHL20) E3 ubiquitin ligase complex to prevent ubiquitin-mediated proteolysis of PML and DAPK1, two tumor suppressors (PubMed:25619834).
Inhibits pre-mRNA splicing (in vitro) (PubMed:9696811).
(Microbial infection) Involved in the alternative splicing of influenza A virus M1 mRNA through interaction with HNRNPK, thereby facilitating the generation of viral M2 protein.

Cellular Location

Cytoplasm; Cytoplasm, cytoskeleton; Nucleus, nucleoplasm. Associated with actin filaments (By similarity).
Localization related to speckle domains which correspond to interchromatin granules and are enriched in factors involved in pre-mRNA splicing (PubMed:9696811).
Following influenza A virus infection, redistribution from speckles to a more diffuse distribution in the nucleoplasm (PubMed:9696811).

Involvement in disease

Immunodeficiency 70 (IMD70):
A primary immunodeficiency clinically characterized by human papillomavirus-associated warts on the hands, feet and face, recurrent bacterial infections, and autoinflammatory features, such as colitis, celiac disease, and retinal vasculitis. Immunologic workup shows decreased CD4+ T cells, decreased CD19+ B cells, and hypogammaglobulinemia. IMD70 inheritance is autosomal dominant with incomplete penetrance.
