ab94102 is a 293T cell transfected lysate in which Human Synphilin 1 has been transiently over-expressed using a pCMV-Synphilin 1 plasmid. The lysate is provided in 1X Sample Buffer. Note: For more details about how the transfected lysate was prepared view preparation notes
Disease: Parkinson disease
Function: Isoform 2 inhibits the ubiquitin ligase activity of SIAH1 and inhibits proteasomal degradation of target proteins. Isoform 2 inhibits autoubiquitination and proteasomal degradation of SIAH1, and thereby increases cellular levels of SIAH. Isoform 2 modulates SNCA monoubiquitination by SIAH1.
PTM: Ubiquitinated; mediated by SIAH1, SIAH2 or RNF19A and leading to its subsequent proteasomal degradation. In the absence of proteasomal degradation, ubiquitinated SNCAIP accumulates in cytoplasmic inclusion bodies. Isoform 2 is subject to limited ubiquitination that does not lead to proteasomal degradation.
Similarity: Contains 6 ANK repeats.
Tissue specificity: Detected in brain (at protein level). Widely expressed, with highest levels in brain, heart and placenta.
