Retinitis pigmentosa 11 (RP11)5 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.

Identified in the spliceosome B complex (PubMed:28781166).

Component of the U4/U6-U5 tri-snRNP complex composed of the U4, U6 and U5 snRNAs and at least PRPF3, PRPF4, PRPF6, PRPF8, PRPF31, SNRNP200, TXNL4A, SNRNP40, DDX23, CD2BP2, PPIH, SNU13, EFTUD2, SART1 and USP39 (PubMed:11867543, PubMed:16723661, PubMed:26912367).

Interacts with a complex formed by SNU13 and U4 snRNA, but not with SNU13 or U4 snRNA alone (PubMed:17412961, PubMed:21784869). The complex formed by SNU13 and PRPF31 binds also U4atac snRNA, a characteristic component of specific, less abundant spliceosomal complexes (PubMed:21784869).

Interacts with PRPF6/U5 snRNP-associated 102 kDa protein (PubMed:11867543, PubMed:17412961, PubMed:26912367).

Component of some MLL1/MLL complex, at least composed of the core components KMT2A/MLL1, ASH2L, HCFC1/HCF1, WDR5 and RBBP5, as well as the facultative components BAP18, CHD8, E2F6, HSP70, INO80C, KANSL1, LAS1L, MAX, MCRS1, MGA, KAT8/MOF, PELP1, PHF20, PRP31, RING2, RUVB1/TIP49A, RUVB2/TIP49B, SENP3, TAF1, TAF4, TAF6, TAF7, TAF9 and TEX10 (PubMed:15960975).

Interacts (via its NLS) with CTNNBL1 (PubMed:21385873).

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
