Biochem/physiol Actions

SIL1 nucleotide exchange factor is an N-linked glycoprotein present in the membrane of endoplasmic reticulum. In coordination with HSPA5, SIL1 regulates proper folding of newly synthesized of proteins and degrades proteins that fail to mature properly. SIL1 is also regulated by glucose and its activity is essential for glucose-stimulated insulin secretion by the pancreatic beta cells. Mutations in SIL1 cause cerebellar ataxia, chronic myopathy, cataracts, delayed motor development and intellectual disability, collectively known as Marinesco-Sjögren syndrome.

Regulation of insulin secretion along the secretory pathway is incompletely understood. We addressed the expression of SIL1, a nucleotide exchange factor for the endoplasmic reticulum (ER) chaperone glucose-regulated protein 78 kD (GRP78), in pancreatic beta cells and investigated whether or not

Marinesco-Sjögren syndrome (MSS) is a rare autosomal recessively inherited disorder with mental retardation (MR). Recently, mutations in the SIL1 gene, encoding a co-chaperone which regulates the chaperone HSPA5, were identified as a major cause of MSS. We here examined the

Marinesco-Sjögren syndrome is a rare autosomal recessive multisystem disorder featuring cerebellar ataxia, early-onset cataracts, chronic myopathy, variable intellectual disability and delayed motor development. More recently, mutations in the SIL1 gene, which encodes an endoplasmic reticulum resident co-chaperone, were identified as

We identified a mammalian BiP-associated protein, BAP, using a yeast two-hybrid screen that shared low homology with yeast Sls1p/Sil1p and mammalian HspBP1, both of which regulate the ATPase activity of their Hsp70 partner. BAP encoded an approximately 54-kDa protein with
