ANKRD54, also known as LIAR, contains 4 ANK repeats. This protein plays an important role in regulating intracellular signaling events associated with erythroid terminal differentiation. This protein interacts (via ankyrin repeat region) with LYN (via SH3-domain) in an activation-independent status of LYN. It forms a multiprotein complex with LYN and HCLS1. ANKRD54 also interacts with TSN2, VAV1, DBNL AND LASP1. Recombinant human ANKRD54 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
