| Tissue Specificity | Widely expressed. There is apparent differential expression of different transcripts. In fetal brain, lung, liver, and kidney, two transcripts of 2 and 5 kb are identified. These transcripts are also seen in all adult tissues analyzed. A larger transcript (12-14 kb) is expressed in prostate, testis, ovary, and colon in the adult. Expression is very low in adult brain tissue. Expressed in peripheral blood lymphocytes. Isoform 1 and isoform 2 are expressed in brain and retina. Isoform 2 is expressed ubiquitously. |
| Function | Mediates the transfer of lipids between membranes at organelle contact sites. Binds phosphatidylinositol 3-phosphate. Functions as a tethering factor in the slow endocytic recycling pathway, to assist traffic between early and recycling endosomes. Involved in the transport of proacrosomal vesicles to the nuclear dense lamina (NDL) during spermatid development. Plays a role in the assembly of the Golgi apparatus, possibly by mediating trafficking to the Golgi membrane. Plays a role in the development of the nervous system, and may be required for neuron projection development. May also play a role during adipose tissue development. Required for maintenance of the ocular lens. |
