Also known as FLJ21816FANCN
Summary
PALB2 (partner and localizer of BRCA2, HGNC:26144) is a protein-coding gene on chromosome 16p12.2, encoding Partner and localizer of BRCA2 (Q86YC2). Plays a critical role in homologous recombination repair (HRR) through its ability to recruit BRCA2 and RAD51 to DNA breaks. In precision oncology, PALB2 Mutation confers sensitivity to Olaparib in Castration-resistant Prostate Carcinoma (CIViC Level A); 6 further curated variant–drug associations are listed below. It is a selective cancer dependency (DepMap: 23.9% of cell lines) and haploinsufficient (ClinGen: sufficient evidence).
This gene encodes a protein that may function in tumor suppression. This protein binds to and colocalizes with the breast cancer 2 early onset protein (BRCA2) in nuclear foci and likely permits the stable intranuclear localization and accumulation of BRCA2.

Function. Plays a critical role in homologous recombination repair (HRR) through its ability to recruit BRCA2 and RAD51 to DNA breaks. Strongly stimulates the DNA strand-invasion activity of RAD51, stabilizes the nucleoprotein filament against a disruptive BRC3-BRC4 polypeptide and helps RAD51 to overcome the suppressive effect of replication protein A (RPA). Functionally cooperates with RAD51AP1 in promoting of D-loop formation by RAD51. Serves as the molecular scaffold in the formation of the BRCA1-PALB2-BRCA2 complex which is essential for homologous recombination. Via its WD repeats is proposed to scaffold a HR complex containing RAD51C and BRCA2 which is thought to play a role in HR-mediated DNA repair. Essential partner of BRCA2 that promotes the localization and stability of BRCA2. Also enables its recombinational repair and checkpoint functions of BRCA2. May act by promoting stable association of BRCA2 with nuclear structures, allowing BRCA2 to escape the effects of proteasome-mediated degradation. Binds DNA with high affinity for D loop, which comprises single-stranded, double-stranded and branched DNA structures. May play a role in the extension step after strand invasion at replication-dependent DNA double-strand breaks; together with BRCA2 is involved in both POLH localization at collapsed replication forks and DNA polymerization activity.
Subunit / interactions. Homooligomer; dissociated upon DNA damage thus allowing association with BRCA1. Oligomerization is essential for its focal accumulation at DNA breaks. Part of a BRCA complex containing BRCA1, BRCA2 and PALB2. Interacts with BRCA1 and this interaction is essential for its function in HRR. Interacts with RAD51AP1 and MORF4L1/MRG15. Component of the homologous recombination repair (HR) complex composed of ERCC5/XPG, BRCA2, PALB2, DSS1 and RAD51. Within the complex, interacts with ERCC5/XPG and BRCA2. Interacts with BRCA2, RAD51C, RAD51 and XRCC3; the interactions are direct and it may serve as a scaffold for a HR complex containing PALB2, BRCA2, RAD51C, RAD51 and XRCC3. Interacts with POLH; the interaction is direct.

Disease relevance. Breast cancer (BC) [MIM:114480] A common malignancy originating from breast epithelial tissue. Breast neoplasms can be distinguished by their histologic pattern. Invasive ductal carcinoma is by far the most common type. Breast cancer is etiologically and genetically heterogeneous. Important genetic factors have been indicated by familial occurrence and bilateral involvement. Mutations at more than one locus can be involved in different families or even in the same case. Disease susceptibility is associated with variants affecting the gene represented in this entry. Breast cancer susceptibility is strongly associated with PALB2 truncating mutations. Conversely, rare missense mutations do not strongly influence breast cancer risk. Fanconi anemia complementation group N (FANCN) [MIM:610832] A disorder affecting all bone marrow elements and resulting in anemia, leukopenia and thrombopenia. It is associated with cardiac, renal and limb malformations, dermal pigmentary changes, and a predisposition to the development of malignancies. At the cellular level it is associated with hypersensitivity to DNA-damaging agents, chromosomal instability (increased chromosome breakage) and defective DNA repair. The disease is caused by variants affecting the gene represented in this entry. Pancreatic cancer 3 (PNCA3) [MIM:613348] A malignant neoplasm of the pancreas. Tumors can arise from both the exocrine and endocrine portions of the pancreas, but 95% of them develop from the exocrine portion, including the ductal epithelium, acinar cells, connective tissue, and lymphatic tissue. Disease susceptibility is associated with variants affecting the gene represented in this entry. Breast-ovarian cancer, familial, 5 (BROVCA5) [MIM:620442] A condition associated with familial predisposition to cancer of the breast and ovaries. Characteristic features in affected families are an early age of onset of breast cancer (often before age 50), increased chance of bilateral cancers (cancer that develop in both breasts, or both ovaries, independently), frequent occurrence of breast cancer among men, increased incidence of tumors of other specific organs, such as the prostate. Disease susceptibility is associated with variants affecting the gene represented in this entry.
Domain organisation. Interaction with BRCA2 occurs through a hydrophobic pocket at the crossover between WD repeats 4 and 5. The coiled coil domain mediates self-association. The chromatin-association motif (ChAM) mediates association with chromatin, probably through nucleosome core particles, independently from binding to D loop, ssDNA or dsDNA structures.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 62 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
