CLIP2

The protein encoded by this gene belongs to the family of cytoplasmic linker proteins, which have been proposed to mediate the interaction between specific membranous organelles and microtubules. This protein was found to associate with both microtubules and an organelle called the dendritic lamellar body. This gene is hemizygously deleted in Williams syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. Alternative splicing of this gene generates 2 transcript variants. [provided by RefSeq, Jul 2008]

Full Name

CAP-Gly Domain Containing Linker Protein 2

Function

Seems to link microtubules to dendritic lamellar body (DLB), a membranous organelle predominantly present in bulbous dendritic appendages of neurons linked by dendrodendritic gap junctions. May operate in the control of brain-specific organelle translocations (By similarity).

Biological Process

Cytoplasmic microtubule organization Source: GO_Central

Cellular Location

Cytoskeleton; Cytoplasm. Localizes preferentially to the ends of tyrosinated microtubules.

Involvement in disease

CLIP2 is located in the Williams-Beuren syndrome (WBS) critical region (PubMed:9799601). WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region. Haploinsufficiency of CLIP2 may be the cause of certain cardiovascular and musculo-skeletal abnormalities observed in the disease. However, it has been demonstrated that haploinsufficiency of this gene alone is not sufficient to cause any of the cognitive or facial features of WBS (PubMed:22608712).
