General annotation (Comments)

Function

Involved in myofibrillogenesis. Seems to be involved in assembly of myosin into sarcomeric A bands in striated muscle. Isoform 3 together with ANK1 isoform Mu17/Ank1.5 may provide a molecular link between the sarcoplasmic reticulum and myofibrils. Ref.1 Ref.9

Catalytic activity

ATP + a protein = ADP + a phosphoprotein.

Cofactor

Magnesium By similarity.

Subunit structure

Isoform 3 interacts with TTN/titin, ANK1 isoform Mu17/ank1.5, and with calmodulin in a Ca2+-independent manner. Associates with fast skeletal muscle myosin By similarity. Ref.1 Ref.5 Ref.7

Subcellular location

Isoform 3: Cytoplasm › myofibril › sarcomere › M line. Cytoplasm › myofibril › sarcomere › Z line. Note: In differentiating skeletal muscle cells, isoform 3 primarily localizes to the sarcomeric M-line and less frequently to the Z-disk. Isoform 3 colocalizes with ANK1 isoform Mu17/ank1.5 at the M-line in differentiated skeletal muscle cells. Ref.7

Involvement in disease

A chromosomal aberration involving OBSCN has been found in Wilms tumor. Translocation t(1;7)(q42;p15) with PTHB1.

Sequence similarities

Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.

Contains 1 DH (DBL-homology) domain.

Contains 4 fibronectin type-III domains.

Contains 55 Ig-like (immunoglobulin-like) domains.

Contains 1 IQ domain.

Contains 1 PH domain.

Contains 2 protein kinase domains.

Contains 1 SH3 domain.

Caution

Initially the name obscurin was used to describe isoform 3 which lacks the kinase domains.

Sequence caution

The sequence CAC85746.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAC85749.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAC85750.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAH71670.2 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAI19283.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAI19284.1 differs from that shown. Reason: Erroneous gene model prediction.

Isoform 4: The sequence BAB13382.1 differs from that shown. Reason: Frameshift at positions 3891, 5061, 5093, 5268, 6352 and 6919.

Alternative products

This entry describes 5 isoforms produced by alternative splicing. [Align] [Select]

Note: Additional isoforms seem to exist.
Isoform 1 (identifier: Q5VST9-1)

Also known as: B; obscurin-MLCK giant kinase;

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: Q5VST9-2)

The sequence of this isoform differs from the canonical sequence as follows:
     5753-5753: S → SS
Isoform 3 (identifier: Q5VST9-3)

Also known as: unc-89-like;

The sequence of this isoform differs from the canonical sequence as follows:
     6221-6620: DTTLERADQE...AQNITPAELQ → VTEQETKVPK...DRDGDEAAQP
     6621-7968: Missing.
Note: Lacks the kinase domain. Initially described as obscurin.
Isoform 4 (identifier: Q5VST9-5)

The sequence of this isoform differs from the canonical sequence as follows:
     3888-3913: PQPVFREPLQSLQAEEGSTATLQCEL → LPARIHSRSEDQGGLRRGHSYTAV
     3914-7968: Missing.
Note: No experimental confirmation available.
