Genes affected

SCHIP1 (HGNC:15678): (schwannomin interacting protein 1) Enables identical protein binding activity. Predicted to be involved in positive regulation of hippo signaling. Predicted to act upstream of or within several processes, including animal organ development; face morphogenesis; and fibroblast migration. Located in several cellular components, including cell junction; cytosol; and nuclear body. [provided by Alliance of Genome Resources, Apr 2022]

SCHIP1 links:

IQCJ-SCHIP1 (HGNC:38842): (IQCJ-SCHIP1 readthrough) This locus represents naturally occurring read-through transcription from the neighboring IQ motif containing J (IQCJ) and schwannomin interacting protein 1 (SCHIP1) genes. Alternative splicing results in multiple transcript variants that are composed of in-frame exons from each individual gene. The resulting fusion products are thought to be components of the multimolecular complexes of axon initial segments and nodes of Ranvier, and they may play a role in calcium-mediated responses.
