PRELID1 (Prelamin A-Related Integral Membrane Protein 1): PRELID1 is a gene involved in the biology of the nuclear envelope. It plays a crucial role in the processing of prelamin A, the precursor to lamin A, which is a vital structural component of the nuclear envelope. Proper function of PRELID1 is essential for maintaining nuclear structure and integrity, and changes in this gene may impact nuclear organisation and cellular function.
