Protein

Leucine-rich repeat and WD repeat-containing protein 1

Gene

LRWD1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Required for G1/S transition. Recruits and stabilizes the origin recognition complex (ORC) onto chromatin during G1 to establish pre-replication complex (preRC) and to heterochromatic sites in post-replicated cells. Binds a combination of DNA and histone methylation repressive marks on heterochromatin. Binds histone H3 and H4 trimethylation marks H3K9me3, H3K20me3 and H4K27me3 in a cooperative manner with DNA methylation. Required for silencing of major satellite repeats. May be important ORC2, ORC3 and ORC4 stability.5 Publications

Post-translational modificationi

Ubiquitinated; undergoes 'Lys-48'-linked polyubiquitination leading to proteasomal degradation. Ubiquitination occurs within the WD repeats at the end of the G1 phase. Ubiquitination may be catalyzed by the CUL4-DDB1 E3 ubiquitin-protein ligase complex and other E3 ligases.1 Publication

Expressioni

Tissue specificityi

Testis-specific. Drastically down-regulated in testis from patients with Sertoli cell-only syndrome (SCOS).1 Publication

Developmental stagei

Regulated in a cell-cycle dependent manner. Highest expression in G1 phase. Expression decreases during S phase, rises again during G2 and drops during mitosis (at protein level). In contrast to protein levels, transcript levels do not show any significant variation during different stages of the cell cycle (PubMed:22935713).2 Publications

Interactioni

Subunit structurei

Integral component of the ORC complex. Directly interacts with CDT1, GMNN and ORC2. Interacts with ORC2 only when non-ubiquitinated; this interaction prevents LRWD1 ubiquitination and degradation. Some of these interactions are regulated in a cell-cycle dependent manner. Interaction with ORC1 occurs predominantly during G1. Association with phosphorylated ORC1 during mitosis is not efficient. Interaction with CDT1 occurs during G1 phase, as well as during mitosis with phosphorylated CDT1. Interaction with GMNN occurs from G1/S to mitosis. Interaction with ORC2 is observed throughout the cell cycle. The stoichiometry of the ORCA/ORC/CDT1/GMNN complex is 1:1:1:2. Interacts with CUL4A and DDB1; this interaction may lead to ubiquitination.5 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
