Switches

This ELM instance is part of the following 1 switching mechanism annotated at the switches.ELM resource:

SWTI000580:

Alternative splicing removes the nuclear localisation signal (NLS) of Breast cancer type 1 susceptibility protein (BRCA1), abrogating binding to Importin subunit alpha-1 (KPNA1) and import into the nucleus. The study compared the full-length Brca1 splice variant (Isoform 1) to the Delta11b isoform (Isoform Delta11b). The shorter isoform is missing exon 11b and differs in a number of ways. Firstly, it lacks an NLS and therefore has a cytoplasmic localisation. Also, when over-expressed, the Delta11b isoform was not toxic, suggesting nuclear localisation is important for Brca1\'s toxic behaviour.
