Cortactin-binding protein 2 is a protein that in humans is encoded by the CTTNBP2 gene.^[5]^[6]

Function[]

This gene encodes a protein with six ankyrin repeats and several proline-rich regions. A similar gene in rat interacts with a central regulator of the actin cytoskeleton.^[6]

Interactions[]

CTTNBP2 has been shown to interact with:

MOBKL3,^[7]
PPP2CA,^[7]
RP6-213H19.1,^[7]
STRN3,^[7] and
STRN.^[7]

Model organisms[]

Model organisms have been used in the study of CTTNBP2 function. A conditional knockout mouse line called Cttnbp2^{tm1b(KOMP)Wtsi} was generated at the Wellcome Trust Sanger Institute.^[8] Male and female animals underwent a standardized phenotypic screen^[9] to determine the effects of deletion.^[10]^[11]^[12]^[13] Additional screens performed: - In-depth immunological phenotyping^[14]
