ANKS4B

Ankyrin repeat and sterile alpha motif domain containing 4B is a protein that in humans is encoded by the ANKS4B gene. ^[1] The gene is also known as HARP (Harmonin-interacting, ankyrin repeat-containing protein). Ankyrin repeats mediate protein-protein interactions in very diverse families of proteins. ^[1]

Model organisms have been used in the study of ANKS4B function. A conditional knockout mouse line, called Anks4b^{tm2a(EUCOMM)Wtsi [7] [8]} was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute. ^{[9] [10] [11]}

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. ^{[5] [12]} Twenty six tests were carried out on mutant mice, but no significant abnormalities were observed. ^[5]
