Protein attributes
| Sequence length | 1011 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | May regulate the disassembly of focal adhesions. Did not bind receptor-like tyrosine phosphatases type 2A. Ref.1 |
| Subunit structure | Forms homodimers and heterodimers. Interacts with S100A4 in a calcium-dependent mode. Ref.7 |
| Tissue specificity | Widely expressed. Absent in liver. Ref.1 |
| Domain | The N-terminal coiled coil regions mediate homodimerization preferentially and heterodimerization type beta/beta. The C-terminal, non-coiled coil regions mediate heterodimerization type beta/alpha and interaction with S100A4. |
| Sequence similarities | Belongs to the liprin family. Liprin-beta subfamily. Contains 3 SAM (sterile alpha motif) domains. |

Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q86W92-1) 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. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 2 (identifier: Q86W92-2) The sequence of this isoform differs from the canonical sequence as follows: 233-263: Missing. 302-302: D → DENFKKKLKEKN 349-349: K → KKGK 544-544: L → LDRKRSASAPTL | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 3 (identifier: Q86W92-3) The sequence of this isoform differs from the canonical sequence as follows: 1-153: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 4 (identifier: Q86W92-4) The sequence of this isoform differs from the canonical sequence as follows: 233-263: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 5 (identifier: Q86W92-5) Also known as: L2; The sequence of this isoform differs from the canonical sequence as follows: 158-170: ELLSRTSLETQKL → VCAEARTKMGFPC 171-1011: Missing. | ||||||
| Note: Due to intron retention. |
