Alternative products
| This entry describes 4 isoforms produced by alternative splicing. [Align] [Select] Note: Additional isoforms seem to exist. | ||||||
| Isoform 3 (identifier: O15438-1) 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. | ||||||
| Isoform 3A (identifier: O15438-2) The sequence of this isoform differs from the canonical sequence as follows: 1194-1527: WLSIGVEFVG...YGMARDAGLA → SEAASLAPCS...ALPLPHFLLI | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 3B (identifier: O15438-3) The sequence of this isoform differs from the canonical sequence as follows: 226-510: MAIYGYRHPL...LKLYAWEPSF → LLNPDPLRGC...IEGLAHQADE 511-1527: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 3S1 (identifier: O15438-4) The sequence of this isoform differs from the canonical sequence as follows: 1-1242: Missing. |
