Nucleolin is a protein that in humans is encoded by the NCL gene.[1][2]

Gene

The human NCL gene is located on chromosome 2 and consists of 14 exons with 13 introns and spans approximately 11kb. The intron 11 of the NCL gene encodes a small nucleolar RNA, termed U20.[3]

Function

Nucleolin (NCL), a eukaryotic nucleolar phosphoprotein, is involved in the synthesis and maturation of ribosomes.[3] The protein is located mainly in dense fibrillar regions of the nucleolus.

Nucleolin is also able to act as a transcriptional coactivator with Chicken Ovalbumin Upstream Promoter Transcription Factor II (COUP-TFII).[4]

Clinical significance

Midkine and pleiotrophin bind to cell-surface nucleolin as a low affinity receptor. This binding can inhibit HIV infection.[5][6]

Nucleolin at the cell surface is the receptor for the Respiratory Syncytial Virus (RSV) fusion protein.[7] Interference with the nucleolin - RSV fusion protein interaction has been shown to be therapeutic against RSV infection in cell cultures and animal models.[8][9][10]

Nucleolin has been shown to interact with:
