background:
LRRC59 (leucine rich repeat containing 59), also known as PRO1855, is a 307 amino acid protein that contains leucine-rich repeats and may play a role in protein binding events throughout the cell. The gene encoding LRRC59 maps to human chromosome 17, which comprises over 2.5% of the human genome and encodes over 1,200 genes. Two key tumor suppressor genes are associated with chromosome 17, namely, p53 and BRCA1. Tumor suppressor p53 is necessary for maintenance of cellular genetic integrity by moderating cell fate through DNA repair versus cell death. Malfunction or loss of p53 expression is associated with malignant cell growth and Li-Fraumeni syndrome. Like p53, BRCA1 is directly involved in DNA repair, though specifically it is recognized as a genetic determinant of early onset breast cancer and predisposition to cancers of the ovary, colon, prostate gland and fallopian tubes.
Function:
Required for nuclear import of FGF1, but not that of FGF2. Might regulate nuclear import of exogenous FGF1 by facilitating interaction with the nuclear import machinery and by transporting cytosolic FGF1 to, and possibly through, the nuclear pores.
Subunit:
Can form homodimers. Interacts with SGOL1. Interacts with FGF1.
Subcellular Location:
Microsome membrane; Single-pass type II membrane protein (By similarity). Endoplasmic reticulum membrane; Single-pass type II membrane protein. Nucleus envelope. Note=Localization in the nuclear envelope depends upon the nuclear import machinery, including KPNB1.
Tissue Specificity:
Widely expressed.
Similarity:
Contains 5 LRR (leucine-rich) repeats.
Database links:
UniProtKB/Swiss-Prot: Q96AG4.1
