General annotation (Comments)
| Function | RNA-binding protein required for embryonic and postnatal development of muscle tissue. May regulate intracellular transport and local translation of certain mRNAs By similarity. |
| Subunit structure | Interacts with FMR1 and FXR2. Interacts with TDRD3, and with CYFIP2 but not with CYFIP1. Ref.7 |
| Subcellular location | |
| Tissue specificity | Expressed in all tissues examined including heart, brain, kidney and testis. Ref.1 |
| Domain | The tandem Tudor domains preferentially recognize trimethylated histone peptides. Ref.14 |
| Post-translational modification | Arg-445 is dimethylated, probably to asymmetric dimethylarginine. |
| Sequence similarities | Belongs to the FMR1 family. Contains 2 Agenet-like domains. Contains 2 KH domains. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] Note: Alternative splicing appears to be tissue-specific. | ||||||
| Isoform 1 (identifier: P51114-1) Also known as: Long; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: P51114-2) Also known as: b; Short; The sequence of this isoform differs from the canonical sequence as follows: 535-539: VTVAD → GKRCD 540-621: Missing. | ||||||
| Note: Contains a phosphoserine at position 524. Contains a phosphoserine at position 528. | ||||||
| Isoform 3 (identifier: P51114-3) The sequence of this isoform differs from the canonical sequence as follows: 1-85: Missing. | ||||||
| Note: No experimental confirmation available. |
